Subject: [PATCH] lan9118: fix multicast filtering
|
|
|
|
The lan9118 emulation tries to compute the multicast index by calling
|
|
directly the crc32() function from zlib, but fails to get the correct
|
|
result.
|
|
|
|
Use the common compute_mcast_idx() function instead, which gives the
|
|
correct result. This fixes IPv6 support.
