2007-02-05driver for Silan SC92031 netdevCesar Eduardo Barros3-0/+1633
This is a driver for the Silan SC92031/Rsltek 8139D NIC chip. This chip is found on at least one counterfeit Encore ENL832-TX-RENT NIC [1], which came with a mini-CD with the 2.4 driver. A slightly older version of the driver was found at [2]. The main difference between them is that the newer one has a small bugfix in the RX path, a lot of gratuitous renaming of functions, all the printable strings changed to show as a "Rsltek 8139D" [sic], and a PCI ID of 8139 instead of 2031. The driver on this patch is a rewrite of the vendor drivers (based mostly on the older one). Changes from the previous patch sent to netdev: - Use MMIO instead of PIO - Changed TX bounce buffers allocation - Use skb_copy_and_csum_dev - Several small bug fixes - Tested for more than just a few minutes each time [1] See http://www.encore-usa.com/faq.php under ENL832-TX-RENT for more information [2] Look for SL_LINUX.ZIP (which is really a .tar.gz) at http://broadbandforum.in/dataone_Intex_LAN_cardlinux-t4207-s15.html [3] To compile on 2.6.17, simply add back the last argument to the interrupt handler in two places, and copy the boolean declarations from 2.6.19 [akpm@osdl.org: build fixes] Signed-off-by: Cesar Eduardo Barros <cesarb@cesarb.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-02-05Spidernet RX Debugging printoutLinas Vepstas1-0/+46

Let's try to avoid some code duplication. - cxgb2 The data are contiguous. Use plain memcpy. - ixf1010/pm3393/vsc7326 The cast of &mac->stats to (u64 *) is not wonderful but it is not clear if it is worth to add an ad-hoc union under the struct cmac_statistics. vsc7326_reg.h suggests that more statistics could be available.

Unconfigured bcm43xx device can hit an assert() during wx_get_rate queries. This is because bcm43xx calls ieee80211softmac_start late (i.e. during open instead of probe). bcm43xx_net_open -> bcm43xx_init_board -> bcm43xx_select_wireless_core -> ieee80211softmac_start Fix is to check that device is running before completing ieee80211softmac_wx_get_rate.

2007-02-05[PATCH] bcm43xx: Interrogate hardware-enable switch and update LEDsLarry Finger5-14/+58
The current bcm43xx driver ignores any wireless-enable switches on mini-PCI and mini-PCI-E cards. This patch implements a new routine to interrogate the radio hardware enabled bit in the interface, logs the initial state and any changes in the switch (if debugging enabled), activates the LED to show the state, and changes the periodic work handler to provide 1 second response to switch changes and to account for changes in the periodic work specs.

2007-02-05[PATCH] zd1211rw: Remove addressing abstractionDaniel Drake8-238/+104
Instead of passing our own custom 32-bit addresses around and translating them, this patch makes all our register address constants absolute and removes the translation. There are two ugly parts: - fw_reg_addr() is needed to compute addresses of firmware registers, as this is dynamic based upon firmware - inc_addr() needs a small hack to handle byte vs word addressing However, both of those are only small, and we don't use fw_regs a whole lot anyway. The bonuses here include simplicity and improved driver readability. Also, the fact that registers are now referenced by 16-bit absolute addresses (as opposed to 32-bit pseudo addresses) means that over 2kb compiled code size has been shaved off. Includes some touchups and sparse fixes from Ulrich Kunitz. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-02-05[PATCH] zd1211rw: Consistency for address space constantsDaniel Drake3-64/+75
The zd1211rw address space has confused me once too many times. This patch introduces the following naming notation: Memory space is split into segments (cr, fw, eeprom) and segments may contain components (e.g. boot code inside eeprom). These names are arbitrary and only for the description below: x_START: Absolute address of segment start (previously these were named such as CR_BASE_OFFSET, but they weren't really offsets unless you were considering them as an offset to 0) x_LEN: Segment length x_y_LEN: Length of component y of segment x x_y_OFFSET: Relative address of component y into segment x. The absolute address for this component is (x_START + x_y_OFFSET) I also renamed EEPROM registers to EEPROM data. These 'registers' can't be written to using standard I/O and really represent predefined data from the vendor. Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.
