Multicast Table Array Algorithm
Receive Address Low - RAL (0x05400 + 8*n; RW)
While "n" is the exact unicast/multicast address entry and it is equals to 0,1,…15.
These registers contain the lower bits of the 48-bit Ethernet address. All 32 bits are
valid.
If the NVM is present the first register (RAL0) is loaded from the NVM.
These registers' addresses have been moved from where they were located in previous
devices. However, for backwards compatibility, these registers can also be accessed at
their alias offsets of 0x0040-0x000BC.
