-Subject: [PATCH] net: rocker: fix an incorrect array bounds check
-
-While processing transmit(tx) descriptors in 'tx_consume' routine
-the switch emulator suffers from an off-by-one error, if a
-descriptor was to have more than allowed(ROCKER_TX_FRAGS_MAX=16)
-fragments. Fix an incorrect bounds check to avoid it.
