Subject: [PATCH net-next 0/2] s390/qeth: Improve handling of OSA RCs 

This two patch series aims to improve how return codes from OSA Express
are handled in the qeth driver.

OSA defines a number of return codes whose meaning is determined by the
issuing command, ie. they are ambiguous. The first patch moves
definitions of all return codes including the ambiguous ones to a single
enum block to aid readability and maintainability.

The second patch implements a mechanism to interpret return codes based
on the issuing command to ensure accurate debug messages. While at it,
remove extern keyword and fix indentation for function declarations to
be in line with Linux kernel coding style.

Aswin Karuvally (2):
  s390/qeth: Move all OSA RCs to single enum
  s390/qeth: Handle ambiguous OSA RCs in s390dbf
