yongari 2010-10-04 20:49:38 UTC FreeBSD src repository Modified files: sys/dev/usb/net if_axe.c Log: SVN rev 213423 on 2010-10-04 20:49:38Z by yongari Move updating TX packet counter to the inside of send loop. axe(4) controllers combine multiple TX requests into single one if there is room in TX buffer of controller. Updating TX packet counter at the end of TX completion resulted in incorrect TX packet counter as axe(4) thought it sent 1 packet. There is no easy way to know how many combined TX were completed in the callback. Because this change updates TX packet counter before actual transmission, it may not be ideal one. But I believe it's better than showing fake 8kpps under high TX load. With this change, TX shows 221kpps on Linksus USB200M. Revision Changes Path 1.22 +11 -1 src/sys/dev/usb/net/if_axe.c
