is_mac_adr_valid()

static uint8_t is_mac_adr_valid ( uint8_t  mac[MAC_ADDR_LEN] )

This function can decide if a given MAC address is valid or not.

Currently, addresses filled with 0xff or 0x00 are not valid.

Parameters

mac	Buffer to the MAC address to check

Returns

0 if address is not valid, otherwise 1

This function will search for a MAC address which can be assigned to a MACPHY.

Parameters

dev	pointer to PCI device
mac	buffer where to store the MAC address
