Subject: [PATCH v2] NetworkPkg/DxeNetLib: Change the order of conditions in IF statement
Date: Wed, 20 May 2020 11:08:47 +0800 [thread overview]
Message-ID: <20200520030847.11416-1-shenglei.zhang@intel.com> (raw)
The condition, NET_HEADSPACE(&(Nbuf->BlockOp[Index])) < Len, is
meaningless if Index = 0. So checking 'Index != 0' should be
performed first in the if statement.
