+Subject: [PATCH] Recalculate AW FCS on WrEndPointConfig command
+
+The WrEndPointConfig command requires recalculating the AW FCS
+on retry, so set the has_aw_fcs parameter to true.
+
+Tested:
+Ran a WrEndPointConfig command with C-states enabled to confirm
+that it correctly retries the command:
+peci_cmds WrEndpointConfigPCILocal 0 13 12 0 0x2d4 0x601e0
