From 0000b81a063b5f3ab82fa18041c28327ce72c312 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Wed, 20 Feb 2019 19:07:32 -0500 Subject: bnxt_en: Wait longer for the firmware message response to complete. The code waits up to 20 usec for the firmware response to complete once we've seen the valid response header in the buffer. It turns out that in some scenarios, this wait time is not long enough. Extend it to 150 usec and use usleep_range() instead of udelay(). Fixes: 9751e8e71487 ("bnxt_en: reduce timeout on initial HWRM calls") Signed-off-by: Michael Chan Signed-off-by: David S.
