57712/578xx devices during handling of encapsulated TSO can properly increase ip id for only one ip header. The patch selects inner header to be increased.

Switch the driver to the managed device API by replacing ioremap() calls with devm_ioremap_resource() (that will also result in calling request_mem_region() which the driver forgot to do until now) and k[mz]alloc() with devm_kzalloc() -- this permits to simplify driver's probe()/remove() method cleanup. We can now remove the ioremap() error messages since the error messages are printed by devm_ioremap_resource() itself. We can also remove the 'bitbang' field from 'struct sh_eth_private' as we don't need it anymore in order to free the memory behind it...

The only place where gfar_configure_coalescing is called with an actual bitmask (other than 0xff) is in gfar_poll (on the hot path). So make gfar_configure_coalescing() static for the buffer processing path, and export gfar_configure_coalescing_all() for the remaining cases that require to set coalescing for all the queues at once (on the slow path).

Split the napi budget fairly among the active queues only, instead of dividing it by the total number of Rx queues assigned to the given interrupt group. Use the h/w indication field RXFi in rstat (receive status register) to identify the active rx queues from the current interrupt group (i.e. receive event occured on ring i, if ring i is part of the current interrupt group). This indication field in rstat, RXFi i=0..7, allows us to find out on which queues of the same interrupt group do we have incomming traffic once we entered the polling routine for the given interrupt group. After servicing the ring i, the corresponding bit RXFi will be written with 1 to clear the active queue indication for that ring.

There are 2 issues with the current napi poll routine, with regards to tx ring cleanup: 1) for multi-queue devices (MQ_MG_MODE), should tx_bit_map != rx_bit_map, which is possible (and supported in h/w) if the DT property "fsl,tx-bit-map" holds a different value than rx_bit_map, the current polling routine will service the wrong Tx queues in this case (i.e. the interrupt group will receive interrupts from tx queues that it will not service) 2) Tx cleanup completion consumes napi budget, whereas the napi budget should be reserved for Rx work only. The patch fixes these issues and provides a clean napi polling routine. Napi poll completion is reached when all the Rx queues have been serviced and there is no Tx work to do.

Fix which was done in the following commit in cpsw driver has to be taken forward to davinci emac driver as well. commit d35162f8 Author: Daniel Mack <zonque@gmail.com> Date: Tue Mar 12 06:31:19 2013 +0000 net: ethernet: cpsw: fix usage of cpdma_check_free_tx_desc() Commit fae50823 ("net: ethernet: davinci_cpdma: Add boundary for rx and tx descriptors") introduced a function to check the current allocation state of tx packets. The return value is taken into account to stop the netqork queue on the adapter in case there are no free slots. However, cpdma_check_free_tx_desc() returns 'true' if there is room in the bitmap, not 'false', so the usage of the function is wrong.
