net: ethernet: ti: cpsw: fix tx vlan priority mapping
[ Upstream commit 5e391dc5a8d801a2410d0032ad4a428d1d61800c ]
The CPDMA_TX_PRIORITY_MAP in real is vlan pcp field priority mapping
register and basically replaces vlan pcp field for tagged packets.
So, set it to be 1:1 mapping. Otherwise, it will cause unexpected
change of egress vlan tagged packets, like prio 2 -> prio 5.
