Description Marian Cingel 2022-09-09 13:16:33 UTC 
'ETHER_EQUAL' performs dereferencing of leading data to 'u_int32_t' for comparison while passed address of 'ether_header->ether_shost' cannot be 4B aligned (has 6B offset from 4B aligned 'ether_header' struct).
Fails at "ng_bridge_get" function while running "/usr/tests/sys/netgraph/bridge basic" in strict aligned mode.
