ethernet: fix mac address increment error
Using "ip neighbor <ip-addr> <mac-addr> static count <count>" to add
static ARP entries will output wrong mac addresses due to lack of
big/little endian conversion. Fix this error by converting mac address
from big endian to little endian before doing the self-increment.
Before patched:
vpp# ip neighbor rdma-0 198.18.1.1 01:aa:bb:cc:dd:e0 static count 5
vpp# show ip neighbor
Time IP Flags Ethernet Interface
4.4400 198.18.1.5 S 05:aa:bb:cc:dd:e0 rdma-0
4.4399 198.18.1.4 S 04:aa:bb:cc:dd:e0 rdma-0
4.4399 198.18.1.3 S 03:aa:bb:cc:dd:e0 rdma-0
4.4399 198.18.1.2 S 02:aa:bb:cc:dd:e0 rdma-0
4.4399 198.18.1.1 S 01:aa:bb:cc:dd:e0 rdma-0
After patched:
vpp# ip neighbor rdma-0 198.18.1.1 01:aa:bb:cc:dd:e0 static count 5
vpp# show ip neighbor
Time IP Flags Ethernet Interface
4.4528 198.18.1.5 S 01:aa:bb:cc:dd:e4 rdma-0
4.4528 198.18.1.4 S 01:aa:bb:cc:dd:e3 rdma-0
4.4528 198.18.1.3 S 01:aa:bb:cc:dd:e2 rdma-0
4.4527 198.18.1.2 S 01:aa:bb:cc:dd:e1 rdma-0
4.4527 198.18.1.1 S 01:aa:bb:cc:dd:e0 rdma-0
