[PATCH net-next 13/14] net: enetc: use alloc_etherdev_mqs() to create netdev for VF driver

[wei.fang at oss.nxp.com]

From: Wei Fang <wei.fang at nxp.com>

The VF driver uses alloc_etherdev_mq() with ENETC_MAX_NUM_TXQS as the
queue count, which forces the TX and RX queue counts to be equal and
uses a compile-time constant rather than the actual hardware capability.

After enetc_get_si_caps() is called, si->num_tx_rings and
si->num_rx_rings reflect the actual number of rings assigned to the VF
by the PF. Switch to alloc_etherdev_mqs() so that the TX and RX queue
counts are set independently based on the real hardware values, avoiding
unnecessary queue structure allocation when the VF has fewer rings than
ENETC_MAX_NUM_TXQS.
