[net-next PATCH 0/3] Energy Efficient Ethernet (eee) support

[net-next PATCH 0/3] Energy Efficient Ethernet (eee) support

[Yuval Mintz]

Hi Dave,

This patch series adds energy efficient ethernet support for the
bnx2x driver (for new chips with appropriate phys). 
It also extends the ethtool API to enable control of the eee feature.

Another patch series has been sent to Ben to allow the ethtool application
to use this new API.

Please consider applying it to 'net-next'.

Thanks,
Yuval Mintz

[net-next PATCH 1/3] Added kernel support in EEE Ethtool commands

[Yuval Mintz]

This patch extends the kernel's ethtool interface by adding support
for 2 new EEE commands - get_eee and set_eee.

Thanks goes to Giuseppe Cavallaro for his original patch adding this support.

Thank to you for having re-worked/re-stored the code I had proposed and
sorry if I was not able to post my patches in time.
Indeed, I had already done some progresses on EEE so I could re-base it
against your work as soon as reviewed.

For example, I could especially contribute on the eee get/set for the
PHY part. I had already sent the patches for phy_device.c (Ben's already
helped me on these) and I am happy to rework them.

Then I could test and verify all (ethtool + phy + user-space
application) with the stmmac d.d. on my platforms.

Is the tx_lpi_timer field for the MAC driver as we discussed in the
past? If yes, so I can use it for the stmmac too.

Hi Peppe,

The short answer is yes.

The API does not specify whether the delay should be made in the MAC
or controller levels, but it should guarantee that if the nic is idle
it should wait that many microseconds prior to asserting its Tx lpi.

Thanks,
Yuval

Perfect! So I'll give you the patches for phy and stmmac asap.

This needs a kernel-doc comment explaining exactly what each of the
fields means.

We *must* initialise all of edata and we should not leave it to the
driver to do.  Otherwise we will be copying back uninitialised data to
userland which (1) might reveal sensitive information stored on the
stack by previous function calls (2) sets the cmd field to the wrong
value (3) sets the reserved fields to random values, making them
unusable for expansion.
