Subject: [PATCH] net: mvneta: fix XDP support if sw bm is used as fallback
|
|
|
|
In order to fix XDP support if sw buffer management is used as fallback
|
|
for hw bm devices, define MVNETA_SKB_HEADROOM as maximum between
|
|
XDP_PACKET_HEADROOM and NET_SKB_PAD and let the hw aligns the IP header
|
|
to 4-byte boundary.
|
|
Fix rx_offset_correction initialization if mvneta_bm_port_init fails in
|
|
mvneta_resume routine
|
|
|
|
Fixes: 0db51da7a8e9 ("net: mvneta: add basic XDP support")
