[ Upstream commit 32374234ab0101881e7d0c6a8ef7ebce566c46c9 ]
In Dmaengine flow, driver maintains struct skbuf_dma_descriptor rings each
element of which corresponds to a skb. In Tx datapath, compare available
space in skb ring with number of skbs instead of skb fragments.
Replace x * (MAX_SKB_FRAGS) in netif_txq_completed_wake() and
netif_txq_maybe_stop() with x * (1 skb) to fix the comparison.
Fixes: 6a91b846af ("net: axienet: Introduce dmaengine support")
