ice: Implement ethtool reset support
Enable ethtool reset support. Ethtool reset flags are mapped to the
E810 reset type:
PF reset:
$ ethtool --reset <ethX> irq dma filter offload
CORE reset:
$ ethtool --reset <ethX> irq-shared dma-shared filter-shared \
offload-shared ram-shared
GLOBAL reset:
$ ethtool --reset <ethX> irq-shared dma-shared filter-shared \
offload-shared mac-shared phy-shared ram-shared
Calling the same set of flags as in PF reset case on port representor
triggers VF reset.
