75 * PC Cards should be using a network specific FUNCE in the CIS to
76 * communicate their MAC address to the driver. However, there are a
77 * large number of NE-2000ish PC Cards that don't do this. Nearly all
78 * of them store the MAC address at a fixed offset into attribute
79 * memory, without any reference at all appearing in the CIS. And
80 * nearly all of those store it at the same location.
82 * This applies only to the older, NE-2000 compatbile cards. The newer
83 * cards based on the AX88x90 or DL100XX chipsets have a specific place
84 * to look for MAC information. And only to those NE-2000 compatible cards
85 * that don't the NE-2000 compatible thing of placing the PROM contents
86 * starting at location 0 of memory.
