Bug Description
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 recognition 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.
__________
Function:
Provide enhanced link speed for OSA networks
Business Case:
Improved performance with OSA networks
Available with kernel 4.20

This function need also be applied to Cosmic and Bionic.
Important for Bionic LTS kernel in support of this new OSA card....
