From: Gilad Ben-Yossef <[email protected]> PACKET_FANOUT and friends is only defined post kernel 3.1, meaning a build against older kernel header fails.
By providing a backwards compatible define for older kernels we allow the build to work, if run time attempts of using the missing functionality on older kernels to degrade to a run-time EINVAL error in init time if the specific feature is used.
