Summary:
- In arp_wait_setup() and arp_wait_cancel(), g_arp_waiters
is protected by a critical section.
- However, I noticed that arp_notify() does not protect the
g_arp_waiters that would cause memory corruption
- This commit fixes the issue.
Impact:
- None

- Tested with spresense:rndis_smp, spresense:rndis

Summary:
- In arp_send(), arp_wait_setup() adds a notify object to g_arp_waiters
which is removed in arp_wait() in normal case.
- However, in timeout and error cases, the object was not removed and
caused memory corruption.
- This commit fixes this issue.
Impact:
- None

Urgent data preceded "normal" data in the TCP payload. If the urgent data is larger than the size of the TCP payload, this indicates that the entire payload is urgent data and that urgent data continues in the next packet.
This case was handled correctly for the case where urgent data was present but was not being handled correctly in the case where the urgent data was NOT present.
