This patch adds support for a new method of signalling the firmware that TSO packets are being sent. The new method removes the need to alter the ip and tcp checksums and allows TSO6 support.

The eTSEC h/w is capable of scatter/gather on the receive side too if MAXFRM > MRBLR, when the allowed maximum Rx frame size is set to be greater than the maximum Rx buffer size (MRBLR). It's about time the driver makes use of this h/w capability, by supporting fixed buffer sizes and Rx S/G. The buffer size given to eTSEC for reception is fixed to 1536B (must be multiple of 64), which is the same default buffer size as before, used to accommodate standard MTU (1500B) size frames. As before, eTSEC can receive frames of up to 9600B. Individual Rx buffers are mapped to page halves (page size for eTSEC systems is 4KB). The skb is built around the first buffer of a frame (using build_skb()). In case the frame spans multiple buffers, the trailing buffers are added as Rx fragments to the skb. The last buffer in frame is marked by the L status flag. A mechanism is in place to reuse the pages owned by the driver (for Rx) for subsequent receptions. Supporting fixed size buffers allows the implementation of Rx S/G, which in turn removes the memory pressure issues the driver had before when MTU was set for jumbo frame reception. Also, in most cases, the Rx path becomes faster due to Rx page reusal, since the overhead of allocating new rx buffers is removed from the fast path.

Use "ndev" instead of "dev", as the rx queue back pointer to a net_device struct, to avoid name clashing with a "struct device" reference. This prepares the addition of a "struct device" back pointer to the rx queue structure. Remove duplicated rxq registration in the process. Move napi_gro_receive() outside gfar_process_frame().

There are several (long standing) problems about how the status field of the rx buffer descriptor (rxbd) is currently handled on the error path: - too many unnecessary 16bit reads of the two halves of the rxbd status field (32bit), also resulting in overuse of endianness convesion macros; - "bdp->status = RXBD_LARGE" makes no sense, since the "large" flag is read only (only eTSEC can write it), and trying to clear the other status bits is also error prone in this context (most of the rx status bits are read only anyway). This is fixed with a single 32bit read of the "status" field, and then the appropriate 16bit shifting is applied to access the various status bits or the rx frame length. Also corrected the use of the RXBD_LARGE flag. Additional fix: "rx_over_errors" stat is incremented instead of "rx_crc_errors" in case of RXBD_OVERRUN occurrence.

Use a more common consumer/ producer index design to improve rx buffer allocation. Instead of allocating a single new buffer (skb) on each iteration, bundle the allocation of several rx buffers at a time. This also opens the path for further memory optimizations. Remove useless check of rxq->rfbptr, since this patch touches rx pause frame handling code as well. rxq->rfbptr is always initialized as part of Rx BD ring init. Remove redundant (and misleading) 'amount_pull' parameter. Signed-off-by: NClaudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The i40e_add_pd_table_entry() routine is being modified to handle both cases where a backing page is passed and where backing page is allocated in i40e_add_pd_table_entry(). For PBLE resource management, it is more efficient for it to manage its backing pages. For VF, PBLE backing page addresses will be send to PF driver for PBLE resource. The i40e_remove_pd_bp() is also modified to not free pre-allocated pages and free only ones which were allocated in i40e_add_pd_table_entry().

Due to an inverted conditional, the driver was marking all of its MAC filters for deletion every time set_rx_mode was called. Depending upon the timing of the calls to set_rx_mode and the processing of the admin queue, the driver would (accidentally) end up with a varying number of functional filters. Correct this logic so that MAC filters are added and removed correctly. Add a check for the driver's "hardware" MAC address so that this filter doesn't get removed incorrectly.

MAC filters for VFs were being programmed with 0 for the VLAN value when there was no VLAN assigned. This is incorrect and actually assigns the VF to VLAN 0.

The driver currently only maps TX and RX queues to a single MSI-X vector per queue pair if there are exactly enough vectors for this. Unfortunately, if we have too many vectors it will fail and allocate queues to vectors in a suboptimal manner. Change the condition check to allow for excess vectors. In this case, the extras just won't be used.

So, while waiting for the cmd to complete, the driver can sleep instead of holding spin_lock_bh() on the mcc_lock.
