Subject: net: Use skb accessors in network drivers
Patch-mainline: v5.4-rc1
Git-commit: d7840976e3915669382c62ddd1700960f348328e
References: jsc#SLE-8371 bsc#1153274
In preparation for unifying the skb_frag and bio_vec, use the fine
accessors which already exist and use skb_frag_t instead of
struct skb_frag_struct.
