Small hack to iterate over all Wistar bridges and enable LLDP/LACP
import subprocess
import re
# return all bridges that contain _br*
BR_INFO = subprocess.Popen("ifconfig | grep _br", shell=True, stdout=subprocess.PIPE)
# regex creates a list of only the bridge names
BRIDGES = re.findall('(t[0-9]+_br[0-9]+?) ', BR_INFO, re.DOTALL)
for bridge in BRIDGES:
print("fixing bridge " + bridge)
command = "echo 65535 > /sys/class/net/" + bridge + "/bridge/group_fwd_mask", shell=True)
