Revision c2af62256e8d6f3c2f72f8678efde75423490c76 authored by Dwip N. Banerjee on 10 December 2020, 01:53:31 UTC, committed by David S. Miller on 10 December 2020, 03:06:10 UTC
We observed that in the error case for batched send_subcrq_indirect() the
driver does not account for the partial success case. This caused Linux to
crash when free_map and pool index are inconsistent.
Driver needs to update the rx pools "available" count when some batched
sends worked but an error was encountered as part of the whole operation.
Also track replenish_add_buff_failure for statistic purposes.
Fixes: 4f0b6812e9b9a ("ibmvnic: Introduce batched RX buffer descriptor transmission")
