During network interface initialization, the NIC driver needs to register its Rx queue with the XDP, to ensure the incoming XDP buffer carries a pointer reference to this info and is stored inside xdp_rxq_info. While this struct isn't tied to XDP prog, if there are any changes in Rx queue, the NIC driver needs to stop the Rx queue by unregistering with XDP before purging and reallocating memory. Drop page_pool destroy during Rx channel reset as this is already handled by XDP during xdp_rxq_info_unreg (Rx queue unregister), failing to do will cause the following warning: warning logs: https://gist.github.com/MeghanaMalladiTI/eb627e5dc8de24e42d7d46572c13e576 Fixes: 46eeb90f03e0 ("net: ti: icssg-prueth: Use page_pool API for RX buffer allocation") Signed-off-by: Meghana Malladi <m-malladi@ti.com> Reviewed-by: Simon Horman <horms@kernel.org> --- Changes from v1(v2-v1): - Included more trace logs for the warning - Collected RB tag from Simon Horman <horms@kernel.org> drivers/net/ethernet/ti/icssg/icssg_common.c | 3 --- 1 file changed, 3 deletions(-)
