Subject: [PATCH net-next v2 00/10] LAN7800 driver improvements
Date: Tue, 24 Aug 2021 19:56:03 +0100 [thread overview]
Message-ID: <20210824185613.49545-1-john.efstathiades@pebblebay.com> (raw)
This patch set introduces a number of improvements and fixes for
problems found during testing of a modification to add a NAPI-style
approach to packet handling to improve performance.
NOTE: the NAPI changes are not part of this patch set and the issues
fixed by this patch set are not coupled to the NAPI changes.
Patch 1 fixes white space and style issues
Patch 2 removes an unused timer
Patch 3 introduces macros to set the internal packet FIFO flow
control levels, which makes it easier to update the levels in future.
Patch 4 removes an unused queue
Patch 5 (updated for v2) introduces function return value checks and
error propagation to various parts of the driver where a return
code was captured but then ignored.
This patch is completely different to patch 5 in version 1 of this patch
set. The changes in the v1 patch 5 are being set aside for the time
being.
Patch 6 updates the LAN7800 MAC reset code to ensure there is no
PHY register access in progress when the MAC is reset. This change
prevents a kernel exception that can otherwise occur.
Patch 7 fixes problems with system suspend and resume handling while
the device is transmitting and receiving data.
Patch 8 fixes problems with auto-suspend and resume handling and
depends on changes introduced by patch 7.
Patch 9 fixes problems with device disconnect handling that can result
in kernel exceptions and/or hang.
Patch 10 limits the rate at which driver warning messages are emitted.
