If anyone has any objections, please let me know. ------------------ From: Eric Dumazet [ Upstream commit 811230cd853d62f09ed0addd0ce9a1b9b0e13fb5 ] When I added sk_pacing_rate field, I forgot to initialize its value in the per cpu unicast_sock used in ip_send_unicast_reply() This means that for sch_fq users, RST packets, or ACK packets sent on behalf of TIME_WAIT sockets might be sent to slowly or even dropped once we reach the per flow limit.
