[RFC ixgbe 0/2] ixgbe: Implement support for ndo_xdp_xmit in skb mode and fix CPU to ring assignment

["Nabil S. Alramli" <dev@nalramli.com>]

Hello Kyle,

Please take a look at this patch that I plan to submit upstream, let me
know if you agree.

Hello ixgbe maintainers,

This patch is a RFC to add the ability to transmit packets using
BPF_F_TEST_XDP_LIVE_FRAMES in skb mode to the ixgbe driver. Today this
functionality does not exist because the ndo_xdp_xmit operation handler,
ixgbe_xdp_xmit, expects a native XDP program in adapter->xdp_prog. This
results in a no-op essentially. To add this support, I use the tx_ring
instead of the xdp_ring and allocate a skb based on the xdpf, and then use
dev_direct_xmit to queue the xdp for tansmission.

May I get feedback on the idea and the approach in this patch?

Thank you.
