Carry flag: 0 Success, AX contains the handle number
Carry flag :1 Failure, DH contains error code
Any incoming Ethernet packet will be accepted for which one or more bits of the packet type matches to the bits of the
installed wildcard packet type. If a packet type of 0xFFFF is installed, any incoming packet will be accepted.
Only one wildcard can be installed at a time. Installing a new wildcard type overwrites the previous.
Delete a wild card handle by installing a wildcard with the packet type 0x0000. "Normal" handlers installed with
ACCESS_TYPE API are not overwritten by installing a wildcard
