Subject: [dpdk-dev] [PATCH v2] bus/pci: resolve multiple NICs address conflicts
Date: Tue, 5 Nov 2019 07:26:13 +0000 [thread overview]
Message-ID: <78A93308629D474AA53B84C5879E84D24B102602@DGGEMM533-MBX.china.huawei.com> (raw)
NIC address conflicts on 64K pagesize when using multiple NICs,
as system will mmap 64K pagesize for NIC,
but dev->mem_resource[i].len is 16K.
