2012-12-10smsc75xx: only set mac address once on bindSteve Glendinning1-2/+8
This patch changes when we decide what the device's MAC address is from per ifconfig up to once when the device is connected. Without this patch, a manually forced device MAC is overwritten on ifconfig down/up. Also devices that have no EEPROM are assigned a new random address on ifconfig down/up instead of persisting the same one.

2012-11-30smsc75xx: expand check_ macrosSteve Glendinning1-159/+576
These macros, while reducing the amount of code, hide flow control and make the code more confusing to follow and review. This patch expands them. It should have no functional effect on the driver.

2012-11-30smsc75xx: don't call usbnet_resume if usbnet_suspend failsSteve Glendinning1-1/+1
If usbnet_suspend returns an error we don't want to call usbnet_resume to clean up, but instead just return the error. If usbnet_suspend *does* succeed, and we have a problem further on, the desired behaviour is still to call usbnet_resume to clean up before returning.

2012-11-28smsc75xx: add support for USB dynamic autosuspendSteve Glendinning1-4/+119
This patch adds support for USB dynamic autosuspend to the smsc75xx driver. This saves virtually no power in the USB device but enables power savings in upstream hosts and the host CPU. Note currently Linux doesn't automatically enable this functionality by default for devices so to test this: echo auto > /sys/bus/usb/devices/2-1.2/power/control where 2-1.2 is the USB bus address of the LAN7500.

2012-05-18USB: Disable hub-initiated LPM for comms devices.Sarah Sharp1-0/+1
Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

The driver used NET_IP_ALIGN to remove some additional padding inside of the rx_fixup function. On many architectures NET_IP_ALIGN defaults to 2 which removed the correct amount of bytes. On MCORE2-machines commit ea812ca1b06113597adcd8e70c0f84a413d97544 introduces a change which sets NET_IP_ALIGN to 0 by default. Which triggered the bug on these machines. This fix introduces a new RXW_PADDING define and uses this instead of NET_IP_ALIGN. The name was taken from the original SMSC7500 driver which is provided by SMSC.

2011-04-29ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny1-3/+4
This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline. All drivers visible to make allyesconfig under x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-04-01net: convert SMSC USB net drivers to hw_featuresMichał Mirosław1-80/+44
There's a race (not fixed here) in smsc75xx in setting RFE_CTL that's not properly handled via rfe_ctl_lock. Spinlock is not a good tool here, as this has to wait for URB completion (or maybe just submission) after issuing register write request. Otherwise, the rfe_ctl might be changed just after spin_unlock() and device left programmed with other value. smsc95xx has increased hard_header_len for the case of TX checksumming. smsc75xx is fixed to advertise IP+IPV6_CSUM instead of HW_CSUM as it does not use csum_start/csum_offset.

2010-04-03net: convert multicast list to list_headJiri Pirko1-3/+3
Converts the list and the core manipulating with it to be the same as uc_list. +uses two functions for adding/removing mc address (normal and "global" variant) instead of a function parameter. +removes dev_mcast.c completely. +exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for manipulation with lists on a sandbox (used in bonding and 80211 drivers) Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
