Merge branch '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Tony Nguyen says:

====================
100GbE Intel Wired LAN Driver Updates 2021-06-17

This series contains updates to ice driver only.

Jake corrects a couple of entries in the PTYPE table to properly
reflect the datasheet and removes unneeded NULL checks for some
PTP calls.

Paul reduces the scope of variables and removes the use of a local
variable.

Shaokun Zhang removes a duplicate function declaration.

Lorenzo Bianconi fixes a compilation warning if PTP_1588_CLOCK is
disabled.

Colin Ian King changes a for loop to remove an unneeded 'continue'.
