How many times same interrupt can be in pending state at a time? (In ARM CM-3)

Could not find the answer to How many times same interrupt can be in pending state at a time? (In ARM CM-3) e.g. : We are processing one interrupt INT_RX, at the same time 3 more packets received. so...

How many TCP frames can be unacknowledged at the same time?

TCPNet is supposed to use buffering which allows for faster data transmission rates. I see however that in some example programs/documentation, the handler of the TCP_STATE_CONNECT state in the send...
