* Send without kernel lockkn2021-01-131-10/+7
| | | | | | | | The output path can run without kernel lock just fine as is. Looking at CVS log, it seems this was not done during import because IFXF_MPSAFE only became a thing afterwards. OK mvs
* Leave default ifq_maxlen handling to ifq_init()kn2020-08-211-2/+1
| | | | | | | | | | | | Most clonable interface drivers (except bridge, enc, loop, pppx, switch, trunk and vlan) initialise the send queue's length to IFQ_MAXLEN during *_clone_create() even though ifq_init(), which is eventually called through if_attach(), does the same. Remove all early "ifq_set_maxlen(&ifq->if_snd, IFQ_MAXLEN);" lines to leave it to ifq_init() and have clonable drivers a tad more in sync. OK mvs

* move counting if_opackets next to counting if_obytes in if_enqueue.dlg2017-01-221-2/+1
| | | | | | | this means packets are consistently counted in one place, unlike the many and various ways that drivers thought they should do it. ok mpi@ deraadt@

rdomains and bridges on the local system. This can be used to route through local rdomains, to create L2 devices (like trunks) between them, and many other things. Discussed with many, with input from mpi@ OK sthen@ phessler@ yasuoka@ mikeb@
