    alc(4): add support for Mikrotik 10/25G NIC

    The new Mikrotik 10/25G NIC is mostly compatible with AR8151 hardware,
    with few exceptions:

    * card supports only 32bit DMA operations
    * card does not support write-one-to-clear semantics for interrupt status
    * MDIO operations can take longer to complete

    This patch adds support for Mikrotik 10/25G NIC to the alc driver
    while maintaining support for all earlier HW.

    The patch was tested with FreeBSD main branch as of commit

    This was tested on Intel i7-4790K system with Mikrotik 10/25G NIC.
    This was tested on Intel i7-4790K system with RB44Ge (AR8151 based 4-port
    to verify backwards compatibility.
