commit e3a19b53cbb0e6738b7a547f262179065b72e3fa upstream.
ConnectX4-Lx uses an inline wqe mode that currently defaults to
requiring the entire L2 header be included in the wqe.
This patch fixes mlx5e_get_inline_hdr_size() to account for
all L2 headers (VLAN, QinQ, etc) using skb_network_offset(skb).
Fixes: e586b3b0baee ("net/mlx5: Ethernet Datapath files")
