[E1000-devel] spanning packet on multiple rx descriptors
Hi, What are the user scenario cases where packet is received on multiple rx descriptors (i guess that usually it is not the case)? How can i force it to happen? Thanks, Benzi. -- ___ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel

Actually all this indicates is that the PF has not been brought up and is likely still down. You just need to do an 'ifconfig eth3 up' and then the VF on 02:10.0 should show link as well when it is brought up.
