2021-11-12selftests: net: switch to socat in the GSO GRE testJakub Kicinski
Commit a985442fdecb ("selftests: net: properly support IPv6 in GSO GRE test") is not compatible with: Ncat: Version 7.80 ( https://nmap.org/ncat ) (which is distributed with Fedora/Red Hat), tests fail with: nc: invalid option -- 'N' Let's switch to socat which is far more dependable. Fixes: 025efa0a82df ("selftests: add simple GSO GRE test") Fixes: a985442fdecb ("selftests: net: properly support IPv6 in GSO GRE test") Tested-by: Andrea Righi <andrea.righi@canonical.com> Link: https://lore.kernel.org/r/20211111162929.530470-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Explicitly pass -6 to netcat when the test is using IPv6 to prevent failures. Also make sure to pass "-N" to netcat to close the socket after EOF on the client side, otherwise we would always hit the timeout and the test would fail.
