2013-02-15igb: Fix for improper exit in igb_get_i2c_clientCarolyn Wyborny1-6/+1
This patch fixes an issue where we check for irq's disabled then exit after explicitly disabling them with spin_lock_irqsave.

2013-02-15igb: Support using build_skb in the case that jumbo frames are disabledAlexander Duyck2-34/+161
This change makes it so that we can enable the use of build_skb for cases where jumbo frames are disabled. The advantage to this is that we do not have to perform a memcpy to populate the header and as a result we see a significant performance improvement.

2013-01-18igb: Add mechanism for detecting latched hardware Rx timestampMatthew Vick4-0/+51
Add a check against possible Rx timestamp freezing in the hardware via watchdog mechanism. This situation can occur when an Rx timestamp has been latched, but the packet has been dropped because the Rx ring is full. Whenever a packet comes in that should be timestamped, the Rx timestamp gets latched into the hardware registers and we will store the jiffy value in the rx_ring. The watchdog will keep track of his own jiffy timer whenever there is no valid timestamp in the registers. If the watchdog detects a valid timestamp in the registers, meaning that no Rx packet has consumed it yet, it will check which time is most recent: the last time in the watchdog or any time in the rx_rings. If the most recent "event" was more than 5 seconds ago, it will flush the Rx timestamp and print a warning message to the syslog.

2013-01-18igb: Add timeout for PTP Tx work itemMatthew Vick4-0/+14
When transmitting a packet that must return a Tx timestamp, a work item gets scheduled to poll for the Tx timestamp being completed in hardware.

2012-11-13igb: Improve performance and reduce size of igb_tx_mapAlexander Duyck1-25/+22
This change is meant to both improve the performance and reduce the size of igb_tx_map. To do this I have expanded the work done in the main loop by pushing first into tx_buffer. This allows us to pull in the dma_mapping_error check, the tx_buffer value assignment, and the initial DMA value assignment to the Tx descriptor. The net result is that the function reduces in size by a little over a 100 bytes and is about 1% or 2% faster.

2012-11-13igb: Update igb Tx flags to improve code efficiencyAlexander Duyck2-33/+45
This change is meant to improve the efficiency of the Tx flags in igb by aligning them with the values that will later be written into either the cmd_type or olinfo. By doing this we are able to reduce most of these functions to either just a simple shift followed by an or in the case of cmd_type, or an and followed by an or in the case of olinfo. In order to avoid type conversion errors I also adjusted the locations where we were switching between CPU and little endian.
