amd-xgbe: Associate Tx SKB with proper ring descriptor (c1530317) · Commits · 戴 / test

The SKB for a Tx packet is associated with an xgbe_ring_data structure in the xgbe_map_tx_skb function. However, it is being saved in the structure after the last structure used when the SKB is mapped. Use the last used structure to save the SKB value. Signed-off-by:
