Merge tag 'net-6.11-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Jakub Kicinski:
"Including fixes from can, bluetooth and wireless.
No known regressions at this point. Another calm week, but chances are
that has more to do with vacation season than the quality of our work.
Current release - new code bugs:
- smc: prevent NULL pointer dereference in txopt_get
- eth: ti: am65-cpsw: number of XDP-related fixes
Previous releases - regressions:
- Revert "Bluetooth: MGMT/SMP: Fix address type when using SMP over
BREDR/LE", it breaks existing user space
- Bluetooth: qca: if memdump doesn't work, re-enable IBS to avoid
later problems with suspend
- can: mcp251x: fix deadlock if an interrupt occurs during
mcp251x_open
- eth: r8152: fix the firmware communication error due to use of bulk
write
- ptp: ocp: fix serial port information export
- eth: igb: fix not clearing TimeSync interrupts for 82580
- Revert "wifi: ath11k: support hibernation", fix suspend on Lenovo
Previous releases - always broken:
- eth: intel: fix crashes and bugs when reconfiguration and resets
happening in parallel
- wifi: ath11k: fix NULL dereference in ath11k_mac_get_eirp_power()
Misc:
- docs: netdev: document guidance on cleanup.h"
