Append new 32-bit key to the selector.

Parameters

cls	classifier to be modifier
val	value to be matched (network byte-order)
mask	mask to be applied before matching (network byte-order)
off	offset, in bytes, to start matching
offmask	offset mask

General selectors define the pattern, mask and offset the pattern will be matched to the packet contents. Using the general selectors you can match virtually any single bit in the IP (or upper layer) header.
