bnxt: support transmit and free of aggregation buffers
This patch adds the following features:
- Support for XDP_TX and XDP_DROP action when using xdp_buff
with frags
- Support for freeing all frags attached to an xdp_buff
- Cleanup of TX ring buffers after transmits complete
- Slight change in definition of bnxt_sw_tx_bd since nr_frags
and RX producer may both need to be used
- Clear out skb_shared_info at the end of the buffer
v2: Fix uninitialized variable warning in bnxt_xdp_buff_frags_free().
