net: stmmac: clear reset value of snps, wr_osr_lmt/snps, rd_osr_lmt before writing

2016-12-06T15:33:48+00:00

WR_OSR_LMT and RD_OSR_LMT have a reset value of 1.
Since the reset value wasn't cleared before writing, the value in the
register would be incorrect if specifying an uneven value for
snps,wr_osr_lmt/snps,rd_osr_lmt.

Zero is a valid value for the properties, since the databook specifies:
maximum outstanding requests = WR_OSR_LMT + 1.

We do not want to change the behavior for existing users when the
property is missing. Therefore, default to 1 if the property is missing,
since that is the same as the reset value.

net: ethernet: stmmac: fix of-node and fixed-link-phydev leaks

2016-12-02T15:42:47+00:00

Make sure to deregister and free any fixed-link phy registered during
probe on probe errors and on driver unbind by adding a new glue helper
function.

Drop the of-node reference taken in the same path also on late probe
errors (and not just on driver unbind) by moving the put from
stmmac_dvr_remove() to the new helper.

ethernet: stmmac: make DWMAC_STM32 depend on it's associated SoC

There's not much point, except compile test, enabling the stmmac
platform drivers unless the STM32 SoC is enabled. It's not
useful without it.

stmmac: fix PTP type ethtool stats

2016-11-16T00:56:17+00:00

This patch fixes the ethtool stats for PTP frames; previous
version does not take care about some message types: i.e.
announce, management and signaling. It also provided a
broken statistic in case of "No PTP message received".
