In the process of tracking down a memory leak when adding/removing FDB entries I had to go through the MAC address configuration code for ixgbe. In the process of doing so I found a number of issues that impacted readability and performance. This change updates the code in general to clean it up so it becomes clear what each step is doing. From what I can tell there a couple of bugs cleaned up in this code. First is the fact that the MAC addresses were being double counted for the PF. As a result once entries up to 63 had been used you could no longer add additional filters. A simple test case for this: for i in `seq 0 96` do ip link add link ens8 name mv$i type macvlan ip link set dev mv$i up done Test script: ethregs -s 0:8.0 | grep -e "RAH" | grep 8000....$ When things are working correctly RAL/H registers 1 - 97 will be consumed. In the failing case it will stop at 63 and prevent any further filters from being added. Signed-off-by:
