Subject: RDMA/hns: Update the IRRL table chunk size in hip08
Patch-mainline: v4.15-rc1
Git-commit: 29a1fe5d70fab7dbdd777458f3c3129f292e61ac
References: bsc#1104427 FATE#326416
As the increase of the IRRL specification in hip08, the IRRL table
chunk size needs to be updated.
This patch updates the IRRL table chunk size to 256k for hip08.
