wifi: mt76: mt7921e: fix random fw download fail

2022-10-29T08:08:35+00:00

[ Upstream commit 29e247ece5d3edfa71495768a9ab5fc7bba76bd4 ]

In case of PCIe interoperability problem shows up, the firmware
payload may be corrupted in download stage. Turn off L0s to keep
fw download process accurately.

net: phy: dp83822: disable MDI crossover status change interrupt

2022-10-29T08:08:35+00:00

[ Upstream commit 7f378c03aa4952507521174fb0da7b24a9ad0be6 ]

If the cable is disconnected the PHY seems to toggle between MDI and
MDI-X modes. With the MDI crossover status interrupt active this causes
roughly 10 interrupts per second.

As the crossover status isn't checked by the driver, the interrupt can
be disabled to reduce the interrupt load.

ionic: catch NULL pointer issue on reconfig

2022-10-29T08:08:34+00:00

[ Upstream commit aa1d7e1267c12e07d979aa34c613716a89029db2 ]

It's possible that the driver will dereference a qcq that doesn't exist
when calling ionic_reconfigure_queues(), which causes a page fault BUG.

If a reduction in the number of queues is followed by a different
reconfig such as changing the ring size, the driver can hit a NULL
pointer when trying to clean up non-existent queues.

Fix this by checking to make sure both the qcqs array and qcq entry
exists bofore trying to use and free the entry.
