Hi! em(4) driver got new sysctl for 'itr' moderation register recently in head and stable/9. Previously, it used the macro DEFAULT_ITR for it.
It seems for me, however, revision 250414 that brought this new feature was quite incomplete: driver still uses DEFAULT_ITR macro instead of sysctl value in the em_initialize_receive_unit() function. Isn't it a bug? And there is no loader tunable like in igb(4) to make a default to eliminate a need of extra reset of each adapter at sysctl time. And it is more convenient to set it in terms of "maximum interrupt per second" than as 'usec/4' unit timeouts, please :-) Eugene Grosbein _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
