[Bug 218894] Network dropouts on em(4) due to jumbo cluster failures
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218894 --- Comment #3 from Kaho Toshikazu --- (In reply to Mike Andrews from comment #2) I don't know the patch resolves the problems originally reported in this PR. 82574L is very slow, but "netstat -m" shows "0/0/0 requests for jumbo clusters denied" with/without the patch. At least, PBA and high/low-water setting for I21[789] is broken because of receive buffer size is too small to save JUMBO frames. PBA should be calculated from MTU, and high/low-water should be calculated from PBA instead of loading immediate values, I think. -- You are receiving this mail because: You are the assignee for the bug. ___ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218894 --- Comment #2 from Mike Andrews --- Dusting this old one off because it's still an issue. This recent commit looks like, from the description anyway (haven't tested), that it might fix the issue: https://reviews.freebsd.org/D16534 -- You are receiving this mail because: You are the assignee for the bug. ___ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218894 Kaho Toshikazu changed: What|Removed |Added CC||[email protected] ||p --- Comment #1 from Kaho Toshikazu --- Created attachment 183084 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=183084&action=edit a patch for jumbo frame and others I don't have a trouble denied some packets temporarily but a trouble dropped many packets with jumbo frames. I use 12-current with a similar patch attached this comment, and the patch does not make everything correct but makes better condition. I have three devices, 82574L, I217-V, I218-V. I don't have any trouble for I21[78] regardless with or without the patch when mtu is 1500. With 9k jumbo, without the patch, scp speed is very slow and dev.em.0.rx_overruns increases. On 82574L, dev.em.0.rx_overruns increases without the patch and dev.em.0.mac_stats.recv_no_buff increases with the patch. Above 6k jumbo, scp speed is almost 10kB/s without the patch and the speed is about 10MB/s with the patch. -- You are receiving this mail because: You are the assignee for the bug. ___ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"
