hi,
the host is a very new Dell PowerEdge R6525 running FreeBSD 13.0,
I have connected ixl0 to an untagged link and ixl1 to a tagged link
I have created 2 bhyve clients, identical, except for the links, one is =
using ixl0 and the other ixl1.340
the untagged boots diskless in about 40 seconds, while the one using the =
tagged one takes 12 minutes!
I compared their dmesgs and they are identical (except for minor diffs =
like mac address)
any ideas?
danny
