Subject: [PATCH 1/1] IB/{qib, hfi1, rdmavt}: Correct ibv_devinfo max_mr value
Git-commit: 35164f5259a47ea756fa1deb3e463ac2a4f10dc9
Patch-mainline: v5.10-rc1
References: bsc#1111666
The command 'ibv_devinfo -v' reports 0 for max_mr.
Fix by assigning the query values after the mr lkey_table has been built
rather than early on in the driver.
Fixes: 7b1e2099adc8 ("IB/rdmavt: Move memory registration into rdmavt")
