    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
      register
    * 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
    f4b38c360e63a6e66245efedbd6c070f9c0aee55

    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
NIC)
    to verify backwards compatibility.
