2012-05-16tokenring: delete all remaining driver supportPaul Gortmaker25-22227/+0
This represents the mass deletion of the of the tokenring support. It gets rid of: - the net/tr.c which the drivers depended on - the drivers/net component - the Kbuild infrastructure around it - any tokenring related CONFIG_ settings in any defconfigs - the tokenring headers in the include/linux dir - the firmware associated with the tokenring drivers. - any associated token ring documentation.

2012-05-12usb/net: rndis: merge media type definitionsLinus Walleij2-7/+7
Let's have a unified table of RNDIS media. We used to have a similar table with NDIS_* prefix from the gadget driver, but since we're only using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows- internal network drivers so what do we care) let's prefix everything with RNDIS. Some of the definitions were conflicting, in one of the defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took the majority vote. Two definition of medium 0x09 calls it "wireless WAN" but one vote for "wireless LAN" but in this case I am sticking with the minority, "Wide Area Network" does not make much sense in this case as far as I can tell. NOTE: latin singular and plural is so screwed up in these defines that it makes my eyes bleed. But I will not attempt to submit a patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED is most probably (erroneously) referring to a singular, unless it can return an array of connected media. I suspect these erroneous plurals are used in documentation and such so I don't want to mess around with things for no functional change.

2012-05-10ixgbe: Hardware Timestamping + PTP Hardware Clock (PHC)Jacob Keller6-1/+861
This patch enables hardware timestamping for use with PTP software by extracting a ns counter from an arbitrary fixed point cycles counter. The hardware generates SYSTIME registers using the DMA tick which changes based on the current link speed. These SYSTIME registers are converted to ns using the cyclecounter and timecounter structures provided by the kernel. Using the SO_TIMESTAMPING api, software can enable and access timestamps for PTP packets. The SO_TIMESTAMPING API has space for 3 different kinds of timestamps, SYS, RAW, and SOF. SYS hardware timestamps are hardware ns values that are then scaled to the software clock. RAW hardware timestamps are the direct raw value of the ns counter. SOF software timestamps are the software timestamp calculated as close as possible to the software transmit, but are not offloaded to the hardware. This patch only supports the RAW hardware timestamps due to inefficiency of the SYS design. This patch also enables the PHC subsystem features for atomically adjusting the cycle register, and adjusting the clock frequency in parts per billion. This frequency adjustment works by slightly adjusting the value added to the cycle registers each DMA tick. This causes the hardware registers to overflow rapidly (approximately once every 34 seconds, when at 10gig link). To solve this, the timecounter structure is used, along with a timer set for every 25 seconds. This allows for detecting register overflow and converting the cycle counter registers into ns values needed for providing useful timestamps to the network stack. Only the basic required clock functions are supported at this time, although the hardware supports some ancillary features and these could easily be enabled in the future. Note that use of this hardware timestamping requires modifying daemon software to use the SO_TIMESTAMPING API for timestamps, and the ptp_clock PHC framework for accessing the clock. The timestamps have no relation to the system time at all, so software must use the posix clock generated by the PHC framework instead.

o Linux stack estimates MSS from skb->len or skb_shinfo(skb)->gso_size. In case of LRO skb->len is aggregate of len of number of packets hence MSS obtained using skb->len would be incorrect. Incorrect estimation of recv MSS would lead to delayed acks in some traffic patterns (which sends two or three packets and wait for ack and only then send remaining packets). This leads to drop in performance. Hence we need to set gso_size to MSS obtained from firmware. o This is fixed recently in firmware hence the MSS is obtained based on capability.
