纯属误解！我之前得到的信息是high-performance-network@openeuler.org high-performance-network@openeuler.org作为社区的邮件列表，所以就通过它将patch往外发了。
现已知该邮件列表的作用。
给大家带来的批量邮件困扰，在这里说声对不起了。😁

提交代码请直接在gitee对应仓库提交PR
本地的DPDK修改在 https://gitee.com/src-openeuler/dpdk 中，先fork然后提交PR，操作与github基本一致

From: Jie Hai haijie1@huawei.com
When packet length in Tx is less than length hardware supported, the minimum frame length in hns3 is used to do padding to avoid hardware error. Currently, this length is fixed by macro, which is very unfavorable for subsequent hardware evolution. So fix it as firmware report.
