Subject: [PATCH] s390/qeth: fix SETIP command handling

commit 1c5b2216fbb973a9410e0b06389740b5c1289171 upstream.

send_control_data() applies some special handling to SETIP v4 IPA
commands. But current code parses *all* command types for the SETIP
command code. Limit the command code check to IPA commands.

Fixes: 5b54e16f1a54 ("qeth: do not spin for SETIP ip assist command")
