X-Git-Tag: v4.14.25~56 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ff01f118d1682aa3bc2a2e0459cd3ce127ffde22;p=platform%2Fkernel%2Flinux-exynos.git doc: Change the min default value of tcp_wmem/tcp_rmem. [ Upstream commit a61a86f8db92923a2a4c857c49a795bcae754497 ] The SK_MEM_QUANTUM was changed from PAGE_SIZE to 4096. And the tcp_wmem/tcp_rmem min default values are 4096.
