Subject: [dpdk-dev] [PATCH v1] net: expand the data size of L3 length to 16 bits
Date: Fri, 4 Sep 2020 13:40:20 +0800
Message-ID: <20200904054020.77648-1-haiyue.wang@intel.com> (raw)
The IPv6 can have large extension header, like the "Segment Routing" may
have (32 + 1) * 8 = 264 bytes, the 8 bits size of L3 length can't handle
this case correctly.
