From: PJ Waskiewicz <pjwaskiew...@gmail.com>
The permanent MAC address is useful to store for things like ethtool,
and when bonding with modes such as active/passive or LACP. This
follows the model of other Ethernet drivers, such as ixgbe.
This was verified on a C220 chassis with the Cisc
update: Fix the spelling of hexidecimal
This updates the help output to specify that CLASSID should be hexidecimal.
This makes sure that a user entering flowid 1:10 gets his flow put into
band 15 (0x10) and knows why.

Using strtoul with a base of 16 converts flowid 10 into 0x10, which makes
it flowid 16. This is interpreted by the kernel incorrectly, and causes
traffic flows above 9 to be classified into band 0 on multiband qdiscs.
This changes the base to 10, which

The socket option for packet sockets to return the original ifindex instead
of the bonded ifindex will not match multicast traffic. Since this socket
option is the most useful for layer 2 traffic and multicast traffic, make
the option multicast-aware.
