The pci transport was stopped twice however due to a workaround in the pci disabling code the disable/enable for first msi interrupt was not balanced. This ended up with irqs not being properly re-enabled and the following print out during recovery: ath10k: failed to receive control response completion, polling.. ath10k: Service connect timeout: -110 ath10k: Could not init core: -110 Legacy interrupt mode was unaffected while msi ranged mode would be partially crippled (it would miss fw indication interrupts but otherwise it worked fine). This fixes completely broken fw recovery for a single msi interrupt mode and fixes subsequent fw crash reports for msi range interrupt mode.

Since the correct implementation would leave us with unacceptably tiny probes, add a workaround which returns a larger value. In current implementation it's possible that unified_scan_lmac and unified_sched_scan_lmac would return -ENOBUFS.

This is not optimal as RS can benefit from the statistics of sent vs. acked of such a BA. This can improve the reaction time of the RS algorithm. Also, an upcoming change in the firmware would cause BA timeout to be reported as a BA notif with 0 acked so this change is required for that as well.

Its primary function is to allocate flows into the TX FIFOs based upon a pre-determined mapping. The driver has some responsibilities to the scheduler, namely initialising and maintaining the hardware registers. This is currently done by directly accessing them, which can cause races with the firmware also accessing the registers. To address this problem, change the driver to no longer directly access the registers but go through the firmware for this if the firmware has support for DQA and thus the new command.

Alex provides two updates to the fm10k driver. First reduces the buffer size to 2k for all page sizes, since most frames only have a 1500 MTU so supporting a buffer size larger than this is somewhat wasteful. Second fixes an issue where the number of transmit queues was not being updated, so added the lines necessary to update the number of transmit queues. Rick Jones provides two patches to convert ixgbe, igb and i40e to use dev_consume_skb_any(). Emil provides two patches for ixgbe, first cleans up a couple of wait loops on auto-negotiation that were not needed. Second fixes an issue reported by Fujitsu/Red Hat, which consolidates the logic behind the dynamically setting of TXDCTL.WTHRESH depending on interrupt throttle rate (ITR) setting regardless of BQL. Ethan Zhao provides a cleanup patch for ixgbe where he noticed a duplicate define. Bernhard Kaindl provides a patch for igb to remove a source of latency spikes by not calling code that uses mdelay() for feeding a PHY stat while being called with a spinlock held. Todd bumps the igb version based on the recent changes. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

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.

Follow commits c706471b2601 ("net: axienet: remove unnecessary ether_setup after alloc_etherdev") and 3c87dcbfb36c ("net: ll_temac: Remove unnecessary ether_setup after alloc_etherdev") and fix the pattern in all remaining ethernet drivers.

The driver being added has been in the staging tree for some time, and will be removed from there in a seperate patch. This one merely disables the staging version to prevent two instances being built. Signed-off-by: Mark Einon <mark.einon@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
