Disclaimer: My first patches to Intel drivers, implemented AF_XDP
zero-copy feature which seemed to be missing for igb. Not sure if it was
a conscious choice to not spend time implementing this for older
devices, nevertheless I send them to the list for review.

The first couple of patches adds helper funcctions to prepare for AF_XDP
zero-copy support which comes in the last couple of patches, one each
for Rx and TX paths.

Sriram Yagnaraman (4):
igb: prepare for AF_XDP zero-copy support
igb: Introduce txrx ring enable/disable functions
igb: add AF_XDP zero-copy Rx support
igb: add AF_XDP zero-copy Tx support
