The non-special multicast filter table (for multicast addresses that are not of the form 01:00:5e:00:00:xx) consists of 256 hash table buckets organised as 64 32-bit words, where the 'accept' bits are in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word. The old code got this right, but the referenced commit broke this by using bits 3 2 1 0 instead. This commit fixes this up. Signed-off-by: Lennert Buytenhek Signed-off-by: David S.
