net: qcom/emac: Replace strlcpy with strscpy The strlcpy should not be used because it doesn't limit the source length. As linus says, it's a completely useless function if you can't implicitly trust the source string - but that is almost always why people think they should use it! All in all the BSD function will lead some potential bugs. But the strscpy doesn't require reading memory from the src string beyond the specified "count" bytes, and since the return value is easier to error-check than strlcpy()'s. In addition, the implementation is robust to the string changing out from underneath it, unlike the current strlcpy() implementation. Thus, We prefer using strscpy instead of strlcpy.

net: qcom/emac: add software control for pause frame mode The EMAC has the option of sending only a single pause frame when flow control is enabled and the RX queue is full. Although sending only one pause frame has little value, this would allow admins to enable automatic flow control without having to worry about the EMAC flooding nearby switches with pause frames if the kernel hangs. The option is enabled by using the single-pause-mode private flag. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

net: qcom/emac: add ethtool support for setting ring parameters Implement the set_ringparam method, which allows the user to specify the size of the TX and RX descriptor rings. The values are constrained to the limits of the hardware. Since the driver does not use separate queues for mini or jumbo frames, attempts to set those values are rejected. If the interface is already running when the setting is changed, then the interface is reset. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

net: qcom/emac: add ethool support for setting pause parameters To support setting the pause parameters, the driver can no longer just mirror the PHY. The set_pauseparam feature allows the driver to force the setting in the MAC, regardless of how the PHY is configured. This means that we now need to maintain an internal state for pause frame support, and so get_pauseparam also needs to be updated. If the interface is already running when the setting is changed, then the interface is reset. Note that if the MAC is configured to enable RX pause frame support (i.e. it transmits pause frames to throttle the other end), but the PHY is configured to block those frames, then the feature will not work. Also some buffer size initialization code into emac_init_adapter(), so that it lives with similar code, including the initializtion of pause frame support.
