This function fixes an accuracy issue with IDT PMIC.

The current reported system power consumption is higher than the actual consumption. With a correction of slope and offset for Vcc and Vnn, the issue is solved.

is_mac_adr_valid()

static uint8_t is_mac_adr_valid ( uint8_t  mac[MAC_ADDR_LEN] )

static

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
