svn commit: r279466 - head/usr.sbin/pciconf

[Ryan Stone]

Here's some sample output for the capability:

ecap 0010[160] = SR-IOV 1 IOV enabled, Memory Space enabled, ARI enabled
                 4 VFs configured out of 128 supported
                 First VF RID Offset 0x0010, VF RID Stride 0x0001
                 VF Device ID 0x154c
                 Page Sizes: 4096 (enabled), 8192, 65536, 262144,
1048576, 4194304

Please note that this looks at the standard PCIe capability in the
device, and so it
cannot be used to check whether a device driver supports SR-IOV in
FreeBSD.  To see
what devices have SR-IOV supported enabled on your machine, check for
device nodes in
/dev/iov.
