Subject: [dpdk-dev] [PATCH v3 0/3] fix 'max-pkt-len' errors
Date: Fri, 22 Jan 2021 09:01:07 +0000	[thread overview]
Message-ID: <20210122090110.50453-1-stevex.yang@intel.com> (raw)
In-Reply-To: <20201223085152.20866-1-stevex.yang@intel.com>

Here fixed 3 issues for 'max-pkt-len':
1. When cmdline option '--max-pkt-len' set the value less then
   '1500 + overhead', the app/testpmd will force to resize the 'max-pkt-len'
   to '1500 + overhead'. However, the user really want to configure
   'max-pkt-len' to a specified value (< 1500 + overhead);

2. If the large value of '--max-pkt-len' gave (e.g.: 8000), and user want to
   reset the value to a small one (e.g.: 1400), it will became invalid due to
   JUMBO_FRAME offload state doesn't change before port started;

3. When rx/tx queue offloads capabilities aren't specified, the rx/tx queue
   setup will be failed once the port offloads changed.

---
v3:
 * rebased code to latest;
 * splited to 3 commits;

v2:
 * moved the update logic to 'rxtx_port_config';
 * added the 'tx_conf' part;
 * optimized the 'default' assignment;
