Revision 12a8541d5c82d17d42424d46ec36929cfef06a10 authored by Yuval Mintz on 29 April 2015, 05:09:49 UTC, committed by David S. Miller on 29 April 2015, 19:49:21 UTC
In a kdump environment interfaces might be re-loaded without a proper unload sequence in the previous running kernel. bnx2x management FW and driver maintains a `pulse' that notifies the FW that the driver is still up and running. Driver load on the kdump kernel should be performed only after the pulse has been out-of-sync long enough for the management FW to identify that the driver has crashed, on which point it will perform some necessary cleanup of the HW. In today's distros kdump loading is quite fast, sometimes too fast for our FW to get out-of-sync. This patch delays the bnx2x's probe during kdump to allow a proper re-load on the kdump kernel.
