net: Optimize skb_tx_hash() by eliminating a comparison
Optimize skb_tx_hash() by eliminating a comparison that executes for every packet. skb_tx_hashrnd initialization is moved to a later part of the startup sequence, namely after the "random" driver is initialized. Rebooted the system three times and verified that the code generates different random numbers each time. Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Signed-off-by: David S.
