描述
What is the issue?
The test applies the buffer size setting, and then checks that the buffer size goes up. If building Tailscale on a machine where the buffer size is already set higher than the Tailscale defaults, the buffer size doesn't go up - it goes down. The test then, obviously, fails.
Steps to reproduce
sysctl -w net.core.wmem_default=16777216, then build Tailscale
