Each command are merged into one: cmd_firewall_parsed.
ADD command format is changed:
p <pipeline ID> firewall add priority <priority> ipv4 <sipaddr>
<sipdepth> <dipaddr> <dipdepth> <sport0> <sport1> <dport0> <dport1>
<proto> <protomask> port <port ID>

and bulk command was modified:
1. firewall add bulk
File line format:
priority <priority> ipv4 <sipaddr> <sipdepth> <dipaddr> <dipdepth>
<sport0> <sport1> <dport0> <dport1> <proto> <protomask> port <port ID>
(protomask is a hex value)
File line example:
priority 0 ipv4 1.2.3.0 24 10.20.30.40 32 0 63 64 127 6 0xF port 3

2. firewall del bulk
File line format:
