Checksumming the IP header of fragments is no different from doing normal IP headers. Discussed with: yongari Note that the definition of CSUM_IP_FRAGS is left in mbuf.h to allow for stable branch source compatibility. 2013-06-18T13:34:37Z Alexander Motin mav@FreeBSD.org 2013-06-18T13:34:37Z urn:sha1:25d9fb4105cb36d9e244718d8f798b15c7e574f1 s/timout/timeout 2013-03-09T02:36:32Z Marius Strobl marius@FreeBSD.org 2013-03-09T02:36:32Z urn:sha1:7b1b32ed4582e7bcdd416c4718d0d79ebaea192d Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs. The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static. 2013-03-09T00:39:54Z Marius Strobl marius@FreeBSD.org 2013-03-09T00:39:54Z urn:sha1:03abd02e1efa33cbb430b395dfdf238e8f3a5f60 Mechanically substitute flags from historic mbuf allocator with malloc(9) flags in sys/dev. 2012-11-23T11:19:43Z Gleb Smirnoff glebius@FreeBSD.org 2012-11-23T11:19:43Z urn:sha1:3e29cda0982706112e7eb8582d03305ff9fdd437 The drbr(9) API appeared to be so unclear, that most drivers in tree used it incorrectly, which lead to inaccurate overrated if_obytes accounting. The drbr(9) used to update ifnet stats on drbr_enqueue(), which is not accurate since enqueuing doesn't imply successful processing by driver. Dequeuing neither mean that. Most drivers also called drbr_stats_update() which did accounting again, leading to doubled if_obytes statistics. And in case of severe transmitting, when a packet could be several times enqueued and dequeued it could have been accounted several times. o Thus, make drbr(9) API thinner. Now drbr(9) merely chooses between ALTQ queueing or buf_ring(9) queueing. - It doesn't touch the buf_ring stats any more. - It doesn't touch ifnet stats anymore. - drbr_stats_update() no longer exists. o buf_ring(9) handles its stats itself: - It handles br_drops itself. - br_prod_bytes stats are dropped. Rationale: no one ever reads them but update of a common counter on every packet negatively affects performance due to excessive cache invalidation. - buf_ring_enqueue_bytes() reduced to buf_ring_enqueue(), since we no longer account bytes. o Drivers handle their stats theirselves: if_obytes, if_omcasts. o mlx4(4), igb(4), em(4), vxge(4), oce(4) and ixv(4) no longer use drbr_stats_update(), and update ifnet stats theirselves. o bxe(4) was the most correct driver, it didn't call drbr_stats_update(), thus it was the only driver accurate under moderate load. Now it also maintains stats itself. o ixgbe(4) had already taken stats from hardware, so just - drop software stats updating. - take multicast packet count from hardware as well. o mxge(4) just no longer needs NO_SLOW_STATS define. o cxgb(4), cxgbe(4) need no change, since they obtain stats from hardware.
