Simplification found by staticcheck:

$ staticcheck ./... | grep S1012
device/cookie.go:90:5: should use time.Since instead of time.Now().Sub (S1012)
device/cookie.go:127:5: should use time.Since instead of time.Now().Sub (S1012)
device/cookie.go:242:5: should use time.Since instead of time.Now().Sub (S1012)
device/noise-protocol.go:304:13: should use time.Since instead of time.Now().Sub (S1012)
device/receive.go:82:46: should use time.Since instead of time.Now().Sub (S1012)

device/send.go:139:5: should use time.Since instead of time.Now().Sub (S1012)

ratelimiter/ratelimiter.go:87:10: should use time.Since instead of time.Now().Sub (S1012)

Change applied using:

$ find . -type f -name "*.go" -exec sed -i "s/Now().Sub(/Since(/g" {} \;

da61947ec3 tun: windows: mitigate infinite loop in Flush()
It's possible that for whatever reason, we keep returning EOF, resulting
in repeated close/open/write operations, except with empty packets.

6a0a3a5406 wintun: revise GetInterface()
- Make foreign interface found error numeric to ease condition
  detection.
- Update GetInterface() documentation.
- Make tun.CreateTUN() quit when foreign interface found before
  attempting to create a Wintun interface with a duplicate name.
  Creation is futile.
