net: stmmac: add per-queue TX & RX coalesce ethtool support
Extending the driver to support per-queue RX and TX coalesce settings in
order to support below commands:
To show per-queue coalesce setting:-
$ ethtool --per-queue <DEVNAME> queue_mask <MASK> --show-coalesce
To set per-queue coalesce setting:-
$ ethtool --per-queue <DEVNAME> queue_mask <MASK> --coalesce \
[rx-usecs N] [rx-frames M] [tx-usecs P] [tx-frames Q]
