[PATCH 5.15 22/82] net: enetc: remove xdp_drops statistic from enetc_xdp_drop()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Fang <wei.fang@xxxxxxx>

commit 412950d5746f7aa139e14fe95338694c1f09b595 upstream.

The xdp_drops statistic indicates the number of XDP frames dropped in
the Rx direction. However, enetc_xdp_drop() is also used in XDP_TX and
XDP_REDIRECT actions. If frame loss occurs in these two actions, the
frames loss count should not be included in xdp_drops, because there
are already xdp_tx_drops and xdp_redirect_failures to count the frame
loss of these two actions, so it's better to remove xdp_drops statistic
from enetc_xdp_drop() and increase xdp_drops in XDP_DROP action.

Fixes: 7ed2bc80074e ("net: enetc: add support for XDP_TX")
