6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ido Schimmel idosch@nvidia.com
[ Upstream commit f520489e99a35b0a5257667274fbe9afd2d8c50b ]
Remove assumptions about shared buffer cell size and instead query the cell size from devlink. Adjust the test to send small packets that fit inside a single cell.
Tested on Spectrum-{1,2,3,4}.
