| H A D | ixgbe_txrx_common.h | diff d0bcacd0a130974f58a56318db7a5ca6a7ba1d5a Tue Oct 02 03:00:32 CDT 2018 Björn Töpel <bjorn.topel@intel.com> ixgbe: add AF_XDP zero-copy Rx support
This patch adds zero-copy Rx support for AF_XDP sockets. Instead of
allocating buffers of type MEM_TYPE_PAGE_SHARED, the Rx frames are
allocated as MEM_TYPE_ZERO_COPY when AF_XDP is enabled for a certain
queue.
All AF_XDP specific functions are added to a new file, ixgbe_xsk.c.
Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS
will allocate a new buffer and copy the zero-copy frame prior passing
it to the kernel stack.
