[Bug] tcprewrite --skipbroadcast option not working

[fklassen]

Describe the bug It appears that this flag is ignored. I tested all the way back to version 3.4.4 and it wasn't working there either

To Reproduce Flag fails on L2 and L3. This tests L2.

1. Run the following on a PCAP file that contains an ARP broadcast

   tcprewrite -b -s 55 -i arp.pcap \  
   --enet-dmac=00:12:13:14:15:16,00:22:33:44:55:66 \
   --enet-smac=00:22:33:44:55:66,00:12:13:14:15:16 \
   -o arp-out.pcap \
   -v -A"-ve"

2. Inspect resultant file

Expected behavior Broadcast MAC address ff:ff:ff:ff:ff:ff should not be altered

Actual results MAC address modified

System (please complete the following information):

• OS: Linux Debian
• OS version: Buster
• Tcpreplay Version 4.4.0 beta1

Additional context

• pcap file: arp.pcap.tar.xz.txt
