From 50f2c01d321df2f44d79d68be8f6ee768eb6a2e0 Mon Sep 17 00:00:00 2001 From: Alexander Motin Date: Sat, 16 Apr 2016 06:36:56 +0000 Subject: [PATCH] Simplify memory allocation for NS requests. Since we no longer need additional buffers for request and response IOCBs, we can increase receive space by 192 bytes, that is enough for fetching 48 more ports. The new limit is 1020 fabric ports per virtual port.
