https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219390 --- Comment #8 from Charles Goncalves <halfling@halfling.com.br> --- (In reply to Krzysztof Galazka from comment #7) Hello Krzysztof! I'm using: Intel 82599ES 10-Gigabit SFI/SFP+ (chip=3D0x10fb8086) I have two machines with crossover connection. test01 <-> test02 On test01 I have ixgbe driver patched and on test02 I don't have. On both machines there is a vlan10 over an ix NIC. Step 1: on machine test02 do a ping to test01 like: ping 10.0.0.1 Step 2: on machine test01 do a tcpdump like: tcpdump -eni netmap:ix0 On Step 2 I'm seeing tcpdump output like: ethertype 802.1Q (0x8100). This i= s an expected behavior. Step 3: on machine test01 do a ping to test02 like: ping 10.0.0.2 Step 4: on machine test02 do a tcpdump like: tcpdump -eni netmap:ix0 On Step 4 I'm seeing tcpdump output like: ethertype IPv4 (0x0800). This is a strange behavior. My inspiration is from em1000 driver: https://github.com/freebsd/freebsd/blob/bb993c697ac4f18efa742ac69db425a5e03= 51117/sys/dev/e1000/if_em.c#L1246+L1249 I hope these steps are clear.
