>
> 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.
