From: Ido Schimmel Date: Fri, 16 Oct 2015 12:01:25 +0000 (+0200) Subject: mlxsw: cmd: Introduce FID-offset flooding tables X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=12fd35ab8af9fe32fce6b36881461d6f62408f70;p=linux-beck.git mlxsw: cmd: Introduce FID-offset flooding tables Packets destined to offloaded netdevs will be classified to FIDs in the device and flooded in case of BUM. The flooding table used is of type FID-offset, which allows one to create different flooding domains for different FIDs and specify the offset in the flooding table for each FID (not necessarily equal to FID or VID). Add support for this flooding table type, by exposing the configuration of the number of tables from this type and their size.
