>Description:
Hardware Supermicro X9SAE with dual network gigabit intel 82574L & 82579LM ports

Software FreeBSD i386 10.0 uses em0 driver

Using ipfilter(ipf) rules with keep state options

Accessing network with telnet, data transfer slow, freezes.

Remove keep state from ipf.rules seems to fix.

Tested with a Realtek 8169 re0 network card & ipf.rules with keep state works ok

Downloaded Intel driver for em0 for BSD 9.0 will not compile.

Need to get working with em driver & keep state in ipfilter.
