## Summary A reply built in the receive path (ICMP echo, ARP, TCP ACK) is dropped when imxrt_transmit() finds every TX descriptor busy. A board that streams UDP keeps the ring full often enough that about 0.5% of pings go unanswered. Stop taking frames off the RX ring and mask RX while the TX ring is full. When a TX completes, unmask RX and drain the ring before polling the stack for more output, so replies are not starved by bulk sends. ## Impact RELEASE ## Testing CI -- This is an automated message from the Apache Git Service.
