[NET] TUN needs CRC32 after adding multicast filtering to it

2005-01-18 Thread Vitezslav Samel
Hi! Just tried to compile 2.6.11-rc1, but it fails with unresolved symbols "bitreverse" etc. Found out that TUN driver needs CRC32 which I haven't compiled in. Following patch fixes this. Please, consider applying. Cheers, Vita diff -urN
