Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue

Tony Nguyen says:

====================
Intel Wired LAN Driver Updates 2021-06-24

This series contains updates to i40e driver only.

Dinghao Liu corrects error handling for failed i40e_vsi_request_irq()
call.

Mateusz allows for disabling of autonegotiation for all BaseT media.

Jesse corrects the multiplier being used on 5Gb speeds for PTP.

Jan adds locking in paths calling i40e_setup_pf_switch() that were
missing it.
