[PATCH net-next v2 2/4] net: marvell: prestera: align flood setting according to latest firmware version
From: Vadym Kochan
Date: Mon May 31 2021 - 12:07:24 EST
From: Vadym Kochan <vkochan@xxxxxxxxxxx>
Latest FW IPC flood message format was changed to configure uc/mc
flooding separately, so change code according to this.
Signed-off-by: Vadym Kochan <vkochan@xxxxxxxxxxx>

Notes:
RFC:
1) Add support for previous FW ABI version (suggested by Andrew Lunn)
