2018-09-12net: ethernet: Fix up drivers masking pause supportAndrew Lunn5-7/+7
PHY drivers don't indicate they support pause. They expect MAC drivers to enable its support if the MAC has the needed hardware. Thus MAC drivers should not mask Pause support, but enable it. Change a few ANDs to ORs. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-12net: bcmgenet: Fix speed selection for reverse MIIAndrew Lunn1-4/+3
The phy supported speed is being used to determine if the MAC should be configured to 100 or 1G. The masking logic is broken. Instead, look at 1G supported speeds to enable 1G MAC support.

2018-09-12net: ethernet: Use phy_set_max_speed() to limit advertised speedAndrew Lunn28-110/+47
Many Ethernet MAC drivers want to limit the PHY to only advertise a maximum speed of 100Mbs or 1Gbps. Rather than using a mask, make use of the helper function phy_set_max_speed().

The driver indicates it can do 10/100 full and half duplex, plus 1G Full. The datasheet indicates 1G half is also supported. So make use of the standard PHY_GBIT_FEATURES.

2018-09-08i40e(vf): remove i40e_ethtool_stats.h header fileJacob Keller4-444/+436
Essentially reverts commit 8fd75c58a09a ("i40e: move ethtool stats boiler plate code to i40e_ethtool_stats.h", 2018-08-30), and additionally moves the similar code in i40evf into i40evf_ethtool.c. The code was intially moved from i40e_ethtool.c into i40e_ethtool_stats.h as a way of better logically organizing the code. This has two problems. First, we can't have an inline function with variadic arguments on all platforms. Second, it gave the appearance that we had plans to share code between the i40e and i40evf drivers, due to having a near copy of the contents in the i40evf/i40e_ethtool_stats.h file. Patches which actually attempt to combine or share code between the i40e and i40evf drivers have not materialized, and are likely a ways off. Rather than fixing the one function which causes build issues, just move this code back into the i40e_ethtool.c and i40evf_ethtool.c files. Note that we also change these functions back from static inlines to just statics, since they're no longer in a header file. We can revisit this if/when work is done to actually attempt to share code between drivers. Alternatively, this stats code could be made more generic so that it can be shared across drivers as part of ethtool kernel work.
