IMHO, it looks good. This patch, however, is a clean-up/enhancement. It doesn't have a Fixes tag, which is good. But I think it should be targeted at net-next (once patch 1/2 has been accepted into net, and net has been merged into net-next; also, given the timing, once net-next reopens as It's likely to close rather soon for the merge window). Perhaps it is possible for the maintainers to pick up patch 1/2, leaving this patch as follow-up. The above notwithstanding, this patch looks good to me. Reviewed-by: Simon Horman <horms@kernel.org>

As Simon correctly noted this isn't a fix, so the patch was supposed to be submitted for the net-next tree. > > Signed-off-by: Xiaolei Wang <xiaolei.wang@windriver.com> > --- > drivers/net/ethernet/stmicro/stmmac/stmmac.h | 1 + > .../net/ethernet/stmicro/stmmac/stmmac_main.c | 18 ++++----- > .../net/ethernet/stmicro/stmmac/stmmac_ptp.c | 22 +++++----- > .../net/ethernet/stmicro/stmmac/stmmac_tc.c | 40 +++++++++---------- > include/linux/stmmac.h | 1 - > 5 files changed, 40 insertions(+), 42 deletions(-) > > diff --git a/drivers/net/ethernet/stmicro/stmmac/stmmac.h b/drivers/net/ethernet/stmicro/stmmac/stmmac.h > index 64b21c83e2b8..e05a775b463e 100644 > --- a/drivers/net/ethernet/stmicro/stmmac/stmmac.h > +++ b/drivers/net/ethernet/stmicro/stmmac/stmmac.h Seeing you'll likely need to resubmit the patch against the net-next tree please move the stmmac_est structure declaration from include/linux/stmmac.h to drivers/net/ethernet/stmicro/stmmac/stmmac.h since there is no longer point in having stmmac_est declared in the former file, and the pointer to the structure is going to be preserved in the stmmac_priv structure now which is declared in the later header file.

Move the EST structure to struct stmmac_priv, because the EST configs don't look like platform config, but EST is enabled in runtime with the settings retrieved for the TC TAPRIO feature also in runtime. So it's better to have the EST-data preserved in the driver private data instead of the platform data storage.
