[PATCH 1/4] NTB: ntb_perf: Increased the number of message retries to 1000

[PATCH 1/4] NTB: ntb_perf: Increased the number of message retries to 1000

[Mehta, Sanju]

From: Sanjay R Mehta <sanju.mehta@amd.com>

while waiting for the peer ntb_perf to initialize scratchpad
registers, local side ntb_perf  might have already exhausted the
maximum number of retries which is currently set to 500. To avoid
this and to give little more time to the peer ntb_perf for scratchpad
initialization, increased the number of retries to 1000

Hi Jon,

The above patch series is not visible in 5.2-rc1 branch. Please let me know when I can expect them in upstream kernel.
