As requested by IBM, adding support for a new IBM Z and LinuxONE (s390x) network card (OSA-Express7S).
The single commit id needed applies cleanly to cosmic and bionic for me.

SRU Justification:

* This is more a request (rather than a bug) to add support for the newest OSA-Express7S (network-) card,
  so that even cosmic and bionic users should be able to benefit from it.

* The support became upstream accepted with 4.20, mainly with commit 

[Test Case]

* Due to the absence of that particular card in our (Canonical) system, the testing is up to IBM.

* The recognition of the card type itself can be done via 'lsqeth | grep card_type',

* and the functionality can be tested by network test tools, like stress-ng.

* A regression test can of course be done on our (Canonical) system.

[Regression Potential] 

* The regression potential can be considered as low since it only affects the s390x platform

* and there only the qeth driver/module.

* The patch itself is less complex and adds mainly lines and fields for the regocnition of the new card.

* The entire code needed is already included in disco and a sniff test was done based on disco's kernel 5.0.
