Subject: [PATCH net-next 0/2] mvpp2: per-cpu buffers
Date: Mon, 2 Sep 2019 12:21:35 +0200 [thread overview]
Message-ID: <20190902102137.841-1-mcroce@redhat.com> (raw)
This patchset workarounds an PP2 HW limitation which prevents to use
per-cpu rx buffers.
The first patch is just a refactor to prepare for the second one.
The second one allocates percpu buffers if the following conditions are met:
- CPU number is less or equal 4
- no port is using jumbo frames
If the following conditions are not met at load time, of jumbo frame is enabled
later on, the shared allocation is reverted.
