Summary:
- I noticed that NFS over TCP does not work with Ubuntu 18.04
- Finally, I found that the record marking packet should not
be sent separately
- This commit fixes this issue
Impact:
- TCP mode only
Testing:
- Tested with NFS server on Ubuntu 18.04 (x86_64)
- Tested with spresense:rndis (defconfig will be updated later)
