ports/net-mgmt/net-snmp-devel/files/patch-interfaces.c
Jun Kuriyama 0ab1ceea8f Fix the problem which cannot get ifPhysAddress value. 
It seems agent/mibgroups/mibII/interfaces.c switched to use new
USE_SYSCTL_IFLIST knob but this does not support ifPhysAddress.

This patch uses old get_phys_address() function from new code.
