octeontx2-pf: Add RSS multi group support
Hardware supports 8 RSS groups per interface. Currently we are using only group '0'. This patch allows user to create new RSS groups/contexts and use the same as destination for flow steering rules. usage: To steer the traffic to RQ 2,3 ethtool -X eth0 weight 0 0 1 1 context new (It will print the allocated context id number) New RSS context is 1 ethtool -N eth0 flow-type tcp4 dst-port 80 context 1 loc 1 To delete the context ethtool -X eth0 context 1 delete When an RSS context is removed, the active classification rules using this context are also removed. Change-log: v4 - Fixed compiletime warning. - Address Saeed's comments on v3. v3 - Coverted otx2_set_rxfh() to use new function. v2 - Removed unrelated whitespace - Coverted otx2_get_rxfh() to use new function.
