Subject: [dpdk-dev] [PATCH 06/11] net/hns3: support a maximun 256 FDIR counter
Date: Tue, 25 Aug 2020 19:53:00 +0800
Message-ID: <20200825115305.58490-7-huwei013@chinasoftinc.com> (raw)
In-Reply-To: <20200825115305.58490-1-huwei013@chinasoftinc.com>

From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

The FDIR counter was used to count the number of FDIR hit, the maximum
number of the counter is 128 based on kunpeng 920, and it was 256 based
on kunpeng 930.

The firmware is responsible to allocate counters for diffent PF devices,
so the available counter number of one PF may be bigger than 128.

Currently, there are two places using the counter in hns3 PMD driver:
1. Configure the counter. Driver uses the command whose opcode is
   HNS3_OPC_FD_AD_OP, now we extend one bit to hold the high bit of
   counter-id in the command format.
2. Query the statistic information of the counter. Driver uses the command
   whose opcode is HNS3_OPC_FD_COUNTER_OP, now the command already support
   16-bit counter-id.
