ionic: unlock queue mutex in error path

2020-08-05T07:58:47Z

[ Upstream commit 59929fbb45e06da7d501d3a97f10a91912181f7c ] On an error return, jump to the unlock at the end to be sure to unlock the queue_lock mutex.

ionic: use mutex to protect queue operations

2020-07-29T08:19:45Z

[ Upstream commit 0925e9db4dc86daf666d9a3d53c7db14ac6d5d00 ] The ionic_wait_on_bit_lock() was a open-coded mutex knock-off used only for protecting the queue reset operations, and there was no reason not to use the real thing. We can use the lock more correctly and to better protect the queue stop and start operations from cross threading. We can also remove a useless and expensive bit operation from the Rx path. This fixes a case found where the link_status_check from a link flap could run into an MTU change and cause a crash.

ionic: keep rss hash after fw update

2020-07-29T08:19:45Z

[ Upstream commit bdff46665ee655600d0fe2a0e5f62ec7853d3b22 ] Make sure the RSS hash key is kept across a fw update by not de-initing it when an update is happening.

ionic: update filter id after replay

2020-07-29T08:19:44Z

[ Upstream commit cc4428c4de8c31f12e4690d0409e0432fe05702f ] When we replay the rx filters after a fw-upgrade we get new filter_id values from the FW, which we need to save and update in our local filter list. This allows us to delete the filters with the correct filter_id when we're done. Fixes: 7e4d47596b68 ("ionic: replay filters after fw upgrade") Signed-off-by: Shannon Nelson Signed-off-by: David S.

ionic: fix up filter locks and debug msgs

2020-07-29T08:19:44Z

[ Upstream commit cbec2153a9a68d011454960ba84887e46e40b37d ] Add in a couple of forgotten spinlocks and fix up some of the debug messages around filter management.

ionic: use offset for ethtool regs data

2020-07-29T08:19:44Z

[ Upstream commit f85ae16f924f92a370b81b4e77862c1c59882fce ] Use an offset to write the second half of the regs data into the second half of the buffer instead of overwriting the first half.

ionic: no link check while resetting queues

2020-07-22T07:34:28Z

commit 3103b6feb4454646558eedc50ece728bc469f341 upstream. If the driver is busy resetting queues after a change in MTU or queue parameters, don't bother checking the link, wait until the next watchdog cycle.

ionic: centralize queue reset code

2020-07-16T06:13:23Z

[ Upstream commit 086c18f2452d0028f81e319f098bcb8e53133dbf ] The queue reset pattern is used in a couple different places, only slightly different from each other, and could cause issues if one gets changed and the other didn't. This puts them together so that only one version is needed, yet each can have slighty different effects by passing in a pointer to a work function to do whatever configuration twiddling is needed in the middle of the reset. This specifically addresses issues seen where under loops of changing ring size or queue count parameters we could occasionally bump into the netdev watchdog. v2: added more commit message commentary Fixes: 4d03e00a2140 ("ionic: Add initial ethtool support") Signed-off-by: Shannon Nelson Acked-by: Jakub Kicinski Signed-off-by: David S.
