From 07d16e4ff194c4cd8e5b939561d0c11e20a777db Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Wed, 15 Apr 2015 12:15:01 +0530 Subject: [PATCH] zynq: gem: Increase the Rx buffer descriptors to 32 Increase the Rx Buffer descriptors to 32. This will avoid Rx buffer descriptors overflow if more packets were received at one shot before we process the received ones. This fixes the issue of intermittent timeouts during tftp on a 1Gb connection with tftp server running on windows.
