[PATCH net 0/2] net: ti: icssg-prueth: fix port config and rx_mode drops

Two independent fixes for the ICSSG PRUETH driver, both hit during
switch offload testing with ports opened/closed in varying order.


Patch 1 fixes icssg_enable_fw_offload() running only once, on the
first port to open (gated by !emacs_initialized), so a sibling port
that opens later never gets its FDB/VLAN table/PVID configured. Each
port now configures itself at open time.

Patch 2 fixes icssg_set_port_state() commands (e.g. promisc/allmulti
flood enable from rx_mode_work) being silently dropped when they race
a PRU/RTU/txPRU firmware reboot, by re-queuing rx_mode_work for all
running ports once the firmware is confirmed back up.
