====================
fix crash issue when setting MQPRIO for VFs
There is a crash issue when setting MQPRIO for ENETC VFs, the root casue
is that ENETC VFs don't like ENETC PFs, they don't have port registers,
so hw->port of VFs is NULL. However, this NULL pointer will be accessed
without any checks in enetc_mm_commit_preemptible_tcs() when configuring
MQPRIO for VFs. Therefore, two patches are added to fix this issue. The
first patch sets ENETC_SI_F_QBU flag only for SIs that support 802.1Qbu.
The second patch adds a check in enetc_change_preemptible_tcs() to ensure
that SIs that do not support 802.1Qbu do not configure preemptible TCs.
