backports: add SPEED_UNKNOWN and DUPLEX_UNKNOWN

This gets us in synch with next-20130618.

This was added via uapi/linux/ethtool.h but using
that file causes some odd issues I simply cannot
resolve right now. I stuff these definitions into
the regular include/linux/ethtool.h for now.

This backports commit 589665f5 added via v3.2.

    bonding: comparing a u8 with -1 is always false

    slave->duplex is a u8 type so the in bond_info_show_slave() when we
    check "if (slave->duplex == -1)", it's always false.
