+Subject: [PATCH 66/93] armv8:pfe Enable UDP checksum for proper tftp
+ operation
+
+1. Add CONFIG_UDP_CHECKSUM flag to perform UDP checksum in S/W
+ instead of hardware
+2. Rx descriptor model changed back to original
+ removed strobe mode
+3. Send more than one dummy packets to bring HIF BD to idle state
+
