2015-01-05be2net: support TX batching using skb->xmit_more flagSathya Perla4-116/+133
This patch uses skb->xmit_more flag to batch TX requests. TX is flushed either when xmit_more is false or there is no more space in the TXQ. Skyhawk-R and BEx chips require an even number of wrbs to be posted. So, when a batch of TX requests is accumulated, the last header wrb may need to be fixed with an extra dummy wrb. This patch refactors be_xmit() routine as a sequence of be_xmit_enqueue() and be_xmit_flush() calls. The Tx completion code is also updated to be able to unmap/free a batch of skbs rather than a single skb. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.

2014-12-30timecounter: keep track of accumulated fractional nanosecondsRichard Cochran1-2/+2
The current timecounter implementation will drop a variable amount of resolution, depending on the magnitude of the time delta. In other words, reading the clock too often or too close to a time stamp conversion will introduce errors into the time values. This patch fixes the issue by introducing a fractional nanosecond field that accumulates the low order bits.

2014-12-26net: Generalize ndo_gso_check to ndo_features_checkJesse Gross4-13/+21
GSO isn't the only offload feature with restrictions that potentially can't be expressed with the current features mechanism. Checksum is another although it's a general issue that could in theory apply to anything. Even if it may be possible to implement these restrictions in other ways, it can result in duplicate code or inefficient per-packet behavior. This generalizes ndo_gso_check so that drivers can remove any features that don't make sense for a given packet, similar to netif_skb_features(). It also converts existing driver restrictions to the new format, completing the work that was done to support tunnel protocols since the issues apply to checksums as well. By actually removing features from the set that are used to do offloading, it solves another problem with the existing interface. In these cases, GSO would run with the original set of features and not do anything because it appears that segmentation is not required.
