ice: Implement RSS settings for GTP using ethtool

Browse source

Following the addition of new GTP RSS hash options to ethtool.h, this patch
implements the corresponding RSS settings for GTP packets in the Intel ice
driver. It enables users to configure RSS for GTP-U and GTP-C traffic over IPv4
and IPv6, utilizing the newly defined hash options.

The implementation covers the handling of gtpu(4|6), gtpc(4|6), gtpc(4|6)t,
gtpu(4|6)e, gtpu(4|6)u, and gtpu(4|6)d traffic, providing enhanced load
distribution for GTP traffic across multiple processing units.
