This patch fixes SRIOV initialization by moving enabling of SRIOV
feature flag before ixgbe_if_init() is called. Also, Clear To Send flag
will not be added to MBX message when PF sends reset request to VF.
Partially. Linux driver does not add IXGBE_VT_MSGTYPE_CTS flag while responding to VF reset message. However, IXGBE_FEATURE_SRIOV flag is FreeBSD specific. It is used in ixgbe_if_init() ( https://github.com/freebsd/freebsd/blob/master/sys/dev/ixgbe/if_ix.c#L3016 ), so it should be set before calling ixgbe_if_init() in context of IOV initialization.
