2018-04-27net: intel: Cleanup the copyright/license headersJeff Kirsher1-21/+1
After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

2017-08-08igb: support BCM54616 PHYJohn W Linville1-0/+1
The management port on an Edgecore AS7712-32 switch uses an igb MAC, but it uses a BCM54616 PHY. Without a patch like this, loading the igb module produces dmesg output like this: [ 3.439125] igb: Copyright (c) 2007-2014 Intel Corporation.

2017-08-08igb: do not drop PF mailbox lock after read of VF messageGreg Edwards1-1/+2
When the PF receives a mailbox message from the VF, it grabs the mailbox lock, reads the VF message from the mailbox, ACKs the message and drops the lock. While the PF is performing the action for the VF message, nothing prevents another VF message from being posted to the mailbox. The current code handles this condition by just dropping any new VF messages without processing them. This results in a mailbox timeout in the VM for posted messages waiting for an ACK, and the VF is reset by the igbvf_watchdog_task in the VM. Given the right sequence of VF messages and mailbox timeouts, this condition can go on ad infinitum. Modify the PF mailbox read method to take an 'unlock' argument that optionally leaves the mailbox locked by the PF after reading the VF message. This ensures another VF message is not posted to the mailbox until after the PF has completed processing the VF message and written its reply.

2015-12-14igb: Improve cable length function for I210, etc.Joe Schultz1-0/+1
Previously, the PHY-specific code to get the cable length for the I210 internal and related PHYs was reporting the cable length of a single pair and reporting it as the min, max, and total cable length. Update it so that all four pairs are checked so the true min, max, and average cable lengths are reported.

2014-10-02igb: remove blocking phy read from inside spinlockBernhard Kaindl1-5/+0
Remove a source of latency spikes (in my case up to 10ms) by not calling code that uses mdelay() for feeding a phy statistic (rx errors for idle symbols - not data -> idle_errors) while being called with a spinlock held. As idle_errors isn't read, this patch only removes unused code and data. Later, more complicated changes may be applied to address the spinlock and allow for some PHY diagnostics by harvesting this PHY stats register fully. This patch is designed to fix the issue and be safe for longterm/stable. For the Intel e1000e driver, the same change was applied in 2008 with commit 23033fad5be0 ("e1000e: remove phy read from inside spinlock"). The mdelay is triggered by HW/SW semaphores, thus it depends on the HW. I've HW that triggers it even when idle. Others may trigger it only e.g. when Ethernet ports aquire or loose the link or on ifconfig up / down. We've noticed this first from delays in frame rx/tx due to the mdelay(). Example command for checking if the issue is triggered: cyclictest -Smp1 (Look for occasional "Max:" values > 4000 or use -b 4000 to stop if greater) It was observed with I350 ports connected to other I350 ports, but not if driver and EEPROM was modified to run the I350 in EEPROM-less mode. phy_stats.idle_errors and .receive_errors (isn't touched) occupy 64 not used bits in the adapter struct: Their allocation may be removed as well.

2014-07-10igb: Workaround for i210 Errata 25: Slow System ClockTodd Fujinaka1-0/+3
On some devices, the internal PLL circuit occasionally provides the wrong clock frequency after power up. The probability of failure is less than one failure per 1000 power cycles. When the failure occurs, the internal clock frequency is around 1/20 of the correct frequency.
