net: dsa: add support for offloading HSR
Add support for offloading of HSR/PRP (IEC 62439-3) tag insertion
tag removal, duplicate generation and forwarding on DSA switches.
Add DSA_NOTIFIER_HSR_JOIN and DSA_NOTIFIER_HSR_LEAVE which trigger calls
to .port_hsr_join and .port_hsr_leave in the DSA driver for the switch.
The DSA switch driver should then set netdev feature flags for the
HSR/PRP operation that it offloads.
NETIF_F_HW_HSR_TAG_INS
NETIF_F_HW_HSR_TAG_RM
NETIF_F_HW_HSR_FWD
NETIF_F_HW_HSR_DUP
