Re: [PATCH v2] selftest: net: Fix error message if empty variable

Fix to avoid cases where the `res` shell variable is empty in script comparisons. The comparison has been modified into string comparison to handle other possible values the variable could assume.

The issue can be reproduced with the command: make kselftest TARGETS=net

It solves the error: ./tfo_passive.sh: line 98: [: -eq: unary operator expected

Notes: v2: edit condition to handle strings

Thanks. This seems more robust to me.
