The current form of Tx coalescing works on a descriptor basis instead of on a packet basis and doesn't take into account TSO packets. Update the Tx coalescing support to work on a packet basis, taking into account the number of packets associated with a TSO transmit. Also, only activate the Tx timer if a timer value is set.

If the Tx engine is told to stop while it is actively processing Tx descriptors it is possible that the Tx descriptor(s) will not be closed out properly. When the Tx engine is restarted this could result in the driver being stuck on the improperly closed descriptor. Update the driver to wait for the Tx engine to be in a stopped or suspended state before issuing the stop command. This has not been an issue to date, but it's a good safe-guard to have.

Micrel KSZ8081 and KSZ8091 PHYs have the RMII Reference Clock Select bit, which is used to select 25 or 50 MHz clock mode. Note that on some revisions of the PHY (e.g. KSZ8081RND) the function of this bit is inverted so that setting it enables 25 rather than 50 MHz mode. Add a new device-tree property "micrel,rmii-reference-clock-select-25-mhz" to describe this. Signed-off-by: NJohan Hovold <johan@kernel.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add generic RMII-Reference-Clock-Select support. Several Micrel PHY have an RMII-Reference-Clock-Select bit to select 25 MHz or 50 MHz clock mode. Recently, support for configuring this through device tree for KSZ8021 and KSZ8031 was added. Generalise this support so that it can be configured for other PHY types as well. Note that some PHY revisions (of the same type) has this bit inverted. This should be either configurable through a new device-tree property, or preferably, determined based on PHY ID if possible. Also note that this removes support for setting 25 MHz mode from board files which was also added by the above mentioned commit 45f56cb82e45 ("net/phy: micrel: Add clock support for KSZ8021/KSZ8031").

Port Key was determined as 16 bits according to the link speed, duplex and user key (which is yet not supported). In the old speed field, 5 bits are for speed [1|10|100|1000|10000]Mbps as below: -------------------------------------------------------------- Port key :| User key | Speed | Duplex| -------------------------------------------------------------- 16 6 1 0 This patch keeps the old layout, but changes AD_LINK_SPEED_BITMASK from bit type to an enum type. In this way, the speed field can expand speed type from 5 to 32. CC: Jay Vosburgh <j.vosburgh@gmail.com> CC: Veaceslav Falico <vfalico@gmail.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: David S.
