The Chelsio T520-BT card work if inserted into a linux host. Now it is placed in FreeBSD 12.0p3 RELEASE host and given out to a CentOS 7.6 guest with pass through. Then I can see this in the guest....
3.466926] cxgb4vf: Chelsio T4/T5/T6 Virtual Function (VF) Network Driver - version 2.0.0-ko
[ 3.466995] cxgb4vf 0000:00:06.0: enabling device (0004 -> 0006)
[ 3.488970] cxgb4vf 0000:00:06.0: bad SGE FL buffer sizes [2048, 4096]
[ 3.489005] cxgb4vf 0000:00:06.0: unable to use adapter parameters: err=-22
[ 3.489112] cxgb4vf: probe of 0000:00:06.0 failed with error -22
So I cannot make the passed though card to work in the guest. Maybe a linux bug. But this card worked with SR-IOV pci pass through from Linux host to a linux guest. But not if the host is FreeBSD. So therefor I wonder....
Any clues very much appreciated
