Hardware support

When you are deploying a new feature, often you will check for hardware support but not always down to the card level, I deployed PBR on a 7600 and read that pbr is supported in hardware with DFC cards. Thing was that the DFC card bit did not register right away, I did not check was I connecting my firewall to DFC cards. While the firewalls are, the eithernet cards that a lot of things use are not. Turns out some are and some are not. So cpu will become interesting when I deploy this.
