Subject: [TCP] FRTO: Incorrectly clears TCPCB_EVER_RETRANS bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=522e7548a9bd40305df41c0beae69448b7620d6b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[TCP] FRTO: Incorrectly clears TCPCB_EVER_RETRANS bit

FRTO was slightly too brave... Should only clear
TCPCB_SACKED_RETRANS bit.
