Merge branch 'ethtool-consolidate-irq-coalescing-other-drivers'

Jakub Kicinski says:

====================
ethtool: consolidate irq coalescing - other drivers

Convert more drivers following the groundwork laid in a recent
patch set [1]. The aim of the effort is to consolidate irq
coalescing parameter validation in the core.

This set converts all the drivers outside of drivers/net/ethernet.

Only vmxnet3 them was checking unsupported parameters.

The aim is to merge this via the net-next tree so we can
convert all drivers and make the checking mandatory.
