> The PMD RSS expansion scheme by default compiles flow rules for all

> by application.
> For example,
> ETH can lead to VLAN, IPv4 or IPv6.
> IPv4 can lead to UDP, TCP, IPv4 or IPv6.
> 
> If application explicitly specified next protocol type, expansion must
> use that option only and not create flows with other protocol types.
> 
> The PMD ignored explicit next protocol values in GRE and VXLAN-GPE.
> 
> The patch updates RSS expansion for GRE and VXLAN-GPE with explicit
> next protocol settings.
