ethtool: support per-queue sub command --coalesce
This patch adds the ability to configure the coalesce settings from
do_scoalesce on a per-queue basis.
For each masked queue the current settings are read, modified, and written
back to the kernel.
Example:
$ sudo ./ethtool --per-queue eth5 queue_mask 0x1 --coalesce
rx-usecs 10 tx-usecs 5
$ sudo ./ethtool --per-queue eth5 queue_mask 0x1 --show-coalesce
