https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D268490 --- Comment #20 from Daniel Duerr <duerrd561@gmail.com> --- (In reply to Kevin Bowling from comment #19) Sure. I started with an up to date `releng/12.4` branch with no changes. The `git revert 6486e9dd8d24b0195facd23d8ca82e17e180cffb` command could not app= ly cleanly without manual conflict resolution. I think I resolved it properly = -- here's the diff between my local version and origin/releng/12.4: [root@nfs src]# git diff origin/releng/12.4 sys/dev/e1000/if_em.c diff --git a/sys/dev/e1000/if_em.c b/sys/dev/e1000/if_em.c index a9ab2fb21535..0f20449db6ec 100644 --- a/sys/dev/e1000/if_em.c +++ b/sys/dev/e1000/if_em.c @@ -1361,7 +1361,7 @@ em_if_init(if_ctx_t ctx) em_setup_vlan_hw_support(ctx); /* Don't lose promiscuous settings */ - em_if_set_promisc(ctx, if_getflags(ifp)); + em_if_set_promisc(ctx, IFF_PROMISC); e1000_clear_hw_cntrs_base_generic(&sc->hw); /* MSI-X configuration for 82574 */ I then proceeded to build and install a GENERIC kernel from this source. Af= ter rebooting on the new kernel, I re-ran the `iperf` tests and the performance= is still terrible: [root@nfs dd]# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 64.0 KByte (default) ------------------------------------------------------------ [ 1] local 172.27.6.135 port 5001 connected with 172.27.6.129 port 50946 [ 2] local 172.27.6.135 port 5001 connected with 172.27.6.129 port 27230 [ 3] local 172.27.6.135 port 5001 connected with 172.27.6.129 port 53346 recv failed: Connection reset by peer [ ID] Interval Transfer Bandwidth [ 1] 0.00-79.38 sec 60.0 Bytes 6.05 bits/sec recv failed: Connection reset by peer [ 2] 0.00-79.38 sec 60.0 Bytes 6.05 bits/sec recv failed: Connection reset by peer [ 3] 0.00-79.38 sec 60.0 Bytes 6.05 bits/sec [SUM] 0.00-122.08 sec 180 Bytes 11.8 bits/sec Did I do the revert wrong? Or do we need to look at other changes that were made in the em driver? --=20 You are receiving this mail because: You are the assignee for the bug.=
