Hello,
after some time i had the possibility to get in touch with RH support,
since the problem was hitting also a setup with RHV 4.0. Seems that
the problem is related to the hardware i'm using, which is a Emulex
554FLB CNA.There is a problem is that the nic uses SR-IOV, which on
that model leads to problems with linux bridge. Disabled SR-IOV on the
nics involved seems to had solved the issue.
