2012-06-28gianfar: Fix RXICr/TXICr programming for multi-queue modeClaudiu Manoil1-6/+4
The correct behavior is to program the interrupt coalescing regs (RXICr/TXICr) in accordance with the Rx/Tx Q's "rx/txcoalescing" flag. That is, if the coalescing flag is 0 for a given Rx/Tx queue then the corresponding coalescing register should be cleared. This behavior is correctly implemented for the single-queue mode (SQ_SG_MODE), but not for the multi-queue mode (MQ_MG_MODE). This fixes the later case.

FCB(Frame Control Block) isn't the part of netdev hard header. Add FCB to hard_header_len will make GRO fail at MAC comparision stage. Signed-off-by: Jiajun Wu <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2012-03-25gianfar: Fix possible overrun and simplify interrupt name field creationJoe Perches1-32/+7
Space allocated for int_name_<foo> is insufficient for maximal device name, expand it. Code to create int_name_<foo> is obscure, simplify it by using sprintf. Found by looking for unnecessary \ line continuations.

2012-03-18gianfar: use netif_tx_queue_stopped instead of __netif_subqueue_stoppedPaul Gortmaker1-1/+1
The __netif_subqueue_stopped() just does the following: struct netdev_queue *txq = netdev_get_tx_queue(dev, queue_index); return netif_tx_queue_stopped(txq); and since we already have the txq in scope, we can just call that directly in this case.

2012-03-15gianfar: delete orphaned version strings and dead macrosPaul Gortmaker1-3/+0
There were two version strings, and neither one was being used. Also in the same proximity were some unused #define that were left over from the past. Delete them all. Signed-off-by: Paul Gortmaker <[email protected]>
2012-03-15gianfar: Add support for byte queue limits.Paul Gortmaker1-3/+16
Add support for byte queue limits (BQL), based on the similar modifications made to intel/igb/igb_main.c from Eric Dumazet in commit bdbc063129e811264cd6c311d8c2d9b95de01231 "igb: Add support for byte queue limits." A local variable for tx_queue->qindex was introduced in gfar_clean_tx_ring, since it is now used often enough to warrant it, and it cleans up the readability somewhat as well.

2012-01-12gianfar: Fix invalid TX frames returned on error queue when time stampingManfred Rudigier1-10/+20
When TX time stamping for PTP messages is enabled on a socket, a time stamp is returned on the socket error queue to the user space application after the frame was transmitted. The transmitted frame is also returned on the error queue so that an application knows to which frame the time stamp belongs. In the current implementation the TxFCB is immediately followed by the frame. Since the eTSEC inserts the TX time stamp 8 bytes after the TxFCB, parts of the frame have been overwritten and an invalid frame was returned on the socket error queue. This patch fixes the described problem by adding additional 16 padding bytes between the TxFCB and the frame for all messages sent from a time stamping enabled socket (other sockets are not affected).

2012-01-12gianfar: Fix missing sock reference when processing TX time stampsManfred Rudigier1-0/+4
When there is not enough headroom in the skb a private copy will be made. However, the private copy had no reference to the socket and consequently no time stamp could be queued on the socket error queue during the skb_tstamp_tx function. This patch fixes this issue by also stealing the sock reference from the original skb after making the private copy. Signed-off-by: Manfred Rudigier <[email protected]> Signed-off-by: David S.
