It looks like CONFIG_L2_PACKET=pcap case was not updated when
l2_packet_init_bridge() was added. The patch below fixes this.
Do you have a specific reason for using libpcap/libdnet
(CONFIG_L2_PACKET=pcap) instead of the default l2_packet_linux.c
implementation (direct use of Linux packet sockets)? libdnet is not
exactly very actively maintained package and it does not seem to be
available in number of Linux distros without manual installation. As
such, I would have expected there to be very minimal, if any, actual use
of l2_packet_pcap.c with wpa_supplicant.
[PATCH] Fix wpa_supplicant build with CONFIG_L2_PACKET=pcap
Commit e6dd8196e5daf39e4204ef8ecd26dd50fdca6040 ('Work around Linux
packet socket regression') forgot to add the l2_packet_init_bridge()
wrapper for l2_packet_pcap.c while updating all the other l2_packet
options. This resulted in wpa_supplicant build failing due to missing
l2_packet_init_bridge() function when using CONFIG_L2_PACKET=pcap in
wpa_supplicant/.config. Fix this by adding the wrapper function.
