Data corruption via IPoIB in connected mode between Linux and FreeBSD

[hiroshi matsuo]

Hi Hans,

Thank you, very good information for me.  I will try it this weekend.

> Did you apply my patch to FreeBSD 12.2 for connected mode?
Maybe not.  Is it included in FreeBSD-12.2-p4?

> Are you using an infiniband router between?
No. I connect two servers directly with one cable.
Under this condition, I think bigger mtu is simply better as far as the
peer (CentOS)
permits.  Is this wrong?
