Message

This series adds XDP multi buffer support, allowing MTU to go beyond
the page size limit.

v2: Fix uninitialized variable warnings in patch 1 and 10.

Dave, please don't apply these patches too quickly so that others can
review them first.  Thanks.

Andy Gospodarek (11):
  bnxt: refactor bnxt_rx_xdp to separate xdp_init_buff/xdp_prepare_buff
  bnxt: add flag to denote that an xdp program is currently attached
  bnxt: refactor bnxt_rx_pages operate on skb_shared_info
  bnxt: rename bnxt_rx_pages to bnxt_rx_agg_pages_skb
  bnxt: adding bnxt_rx_agg_pages_xdp for aggregated xdp
  bnxt: set xdp_buff pfmemalloc flag if needed
  bnxt: change receive ring space parameters
  bnxt: add page_pool support for aggregation ring when using xdp
  bnxt: adding bnxt_xdp_build_skb to build skb from multibuffer xdp_buff
  bnxt: support transmit and free of aggregation buffers
  bnxt: XDP multibuffer enablement

Please widen the CC list on v3. People who had been involved in XDP
mbuf discussions would be good to CC.
