All packets are dropped. --------------------------------------------------------- eth2 Link encap:Ethernet HWaddr 00:30:18:A9:F4:01 inet addr:10.23.202.49 Bcast:10.23.202.55 Mask:255.255.255.248 inet6 addr: fe80::230:18ff:fea9:f401/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:15642592 errors:0 dropped:251658225 overruns:0 frame:0 TX packets:18904013 errors:0 dropped:92 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1555731278 (1483.6 Mb) TX bytes:1855203093 (1769.2 Mb) Interrupt:19 Base address:0xc800 --------------------------------------------------------- It seems to be different kind of bug than this one: https://bugzilla.kernel.org/show_bug.cgi?id=16276
