The if_bnxt driver initialises |.isc_nrxd_max = {INT32_MAX, INT32_MAX, INT32_MAX},|, so presumably that’s the cause. I don’t know what a sane value would be though. I’ve defaulted to 4096 (because that’s what some other iflib users seems to do) for now, and that seems to work. It doesn’t panic and I can get traffic through it at least:
You seem to be setting the max, not the default, and 4K max descriptors on a 100g device is going to basically cripple it.
How about setting to the next power of 2 below max int so as to keep with the authors intent?
If we don't already have a macro, something like (INT32_MAX >> 1) + 1 Drew _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
