Subject: [PATCH net-next v2 9/9] net: ethernet: ti: ale: add support for multi port k3 cpsw versions

The TI J721E (CPSW9g) ALE version is similar, in general, to Sitara AM3/4/5
CPSW ALE, but has more extended functions and different ALE VLAN entry
format.

This patch adds support for for multi port TI J721E (CPSW9g) ALE variant.
