net/dcb: Add an optional max rate attribute
Although not specified in 8021Qaz spec, it could be useful to enable drivers whose HW supports setting a rate limit for an ETS TC. This patch adds this optional attribute to DCB netlink. To use it, drivers should implement and register the callbacks ieee_setmaxrate and ieee_getmaxrate. The units are 64 bits long and specified in Kbps to enable usage over both slow and very fast networks. Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.
