Summary:
- I noticed that an NFS connection is automatically dropped.
- Actually, this happens in TCP mode if no traffic happens
for 600 seconds.
- I confirmed that the NFS client on Ubuntu automatically
reconnects to the NFS server when an RPC call failed.
- This commit adds the same behavior to fix the issue.
Impact:
- NFS client in TCP mode
Testing:
- Tested with spresense:rndis_smp
