2014-04-28lcs: replace PTR_RET with PTR_ERR_OR_ZERODuan Jiong1-1/+1
PTR_RET is deprecated. Do not recommend its usage anymore. Use PTR_ERR_OR_ZERO instead.

2014-04-28qeth: Fix default queue setting in priority queueingStefan Raspl1-3/+5
The default queue for queueing modes prio_queueing_prec and prio_queueing_tos is supposed to be QETH_DEFAULT_QUEUE. However, neither mode will reset the default default_out_queue value when enabled, leaving a previously set value activate as the default. E.g. enabling one of the fixed queueing modes, e.g. no_prio_queueing:0, and successively switching to any of the prio_queueing_* modes will leave default_out_queue at the previous (wrong) value 0.

2014-04-28ptp: validate the requested frequency adjustment.Richard Cochran1-1/+4
PTP Hardware Clock drivers specify a maximum frequency adjustment that their clocks can accommodate. Normally, user space programs will want to respect the advertised limits. However, no kernel or driver code checks that the dialed frequency offset is within the bounds, and out of range values can lead to surprising results. This patch fixes the issue by rejecting bad values. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-04-27qlcnic: Optimize MAC learning codeShahed Shaikh1-12/+7
* Use rx_mac_learn instead of mac_learn and eSwitch flag check in Rx path of 82xx adapter. * Check for MAC filter overrun only after driver scans through cached MAC address list. This will help to update the time stamp of cached MAC addresses even if adapter runs out of MAC address filter limit. * Remove expensive log thrown by driver when MAC address filters are exhausted Signed-off-by: Shahed Shaikh <shahed.shaikh@qlogic.com> Signed-off-by: David S.

As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.

On some Kvaser hardware, the firmware returns extra messages after the request for card info. For instance on a Leaf Light v2: --> CMD_GET_CARD_INFO <-- CMD_USB_THROTTLE <-- CMD_GET_CARD_INFO2 <-- CMD_GET_CARD_INFO_REQ When it happens, the probing function fails because we only read the first usb message. To overcome this issue, we add a mechanism of retries to the kvaser_usb_wait_msg() function. I tested this patch with the following hardware: - Kvaser Leaf Light - Kvaser Leaf Light v2 - Kvaser USBCan R This patch is necessary for the Leaf Light v2 hardware.

The MCP251x utilizes an oscillator startup timer (OST), which holds the chip in reset, to insure that the oscillator has stabilized before the internal state machine begins to operate. The OST maintains reset for the first 128 OSC clock cycles after power up or reset. So, this patch removes unnecessary loops and reduce delay for power on and reset to the safe value.
