-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
