To View Rules for a Specific Interface

When firewall rules exist for a Solarflare interface, and only while they exist, a directory for the interface will be created in:

/proc/driver/sfc_resource

Rules for a specific interface will be found in the firewall_rules file. For example:

cat /proc/driver/sfc_resource/eth3/firewall_rules
if=eth3 rule=0 protocol=tcp local_ip=0.0.0.0/0.0.0.0 remote_ip=0.0.0.0/0.0.0.0 local_port=5201-5201 remote_port=0-65535 action=DECELERATE
if=eth3 rule=1 protocol=tcp local_ip=0.0.0.0/0.0.0.0 remote_ip=0.0.0.0/0.0.0.0 local_port=5201-5201 remote_port=0-65535 action=DECELERATE
if=eth3 rule=2 protocol=tcp local_ip=0.0.0.0/0.0.0.0 remote_ip=0.0.0.0/0.0.0.0 local_port=5201-5201 remote_port=72-72 action=DECELERATE
if=eth3 rule=3 protocol=tcp local_ip=0.0.0.0/0.0.0.0 remote_ip=0.0.0.0/0.0.0.0 local_port=80-88 remote_port=0-65535 action=DECELERATE
