Revision 51a83391d77bb0f7ff0aef06ca4c7f5aa9e80b4c authored by Dimitris Michailidis on 26 July 2022, 21:59:23 UTC, committed by Paolo Abeni on 28 July 2022, 10:54:10 UTC
The current implementation of fun_xdp_tx(), used for XPD_TX, is
incorrect in that it takes an address/length pair and later releases it
with page_frag_free(). It is OK for XDP_TX but the same code is used by
ndo_xdp_xmit. In that case it loses the XDP memory type and releases the
packet incorrectly for some of the types. Assorted breakage follows.

Change fun_xdp_tx() to take xdp_frame and rely on xdp_return_frame() in
reclaim.
