When the DEBUG preprocessor macro is defined the ps3_gelic_net driver build fails due to an undeclared routine gelic_descr_get_status(). This problem was introduced during the code cleanup of commit 6b0c21ce (net: Fix p3_gelic_net sparse warnings), which re-arranged the ordering of some of the gelic routines. This change just moves the gelic_descr_get_status() routine up in the ps3_gelic_net.c source file. There is no functional change.

Florian Fainelli says: ==================== net: broadcom MDIO support for broken turn-around These two patches update the GENET and UniMAC MDIO controllers to deal with PHYs that are known to have a broken turn-around bug (e.g: BCM53125 and others) This utilizes the infrastructure that code recently added to do that in 'net-next'. Note that the changes look nearly identical and I will try to address the MDIO code duplication between GENET and UniMAC in a future patch series.

Some Ethernet PHYs/switches such as Broadcom's BCM53125 have a hardware bug which makes them not release the MDIO line during turn-around time. This gets flagged by the UniMAC MDIO controller as a read failure, and we fail the read transaction. Check the MDIO bus phy_ignore_ta_mask bitmask for the PHY we are reading from and if it is listed in this bitmask, ignore the read failure and proceed with returning the data we read out of the controller.

Ethernet AVB device includes the gPTP timer, so we can implement a PTP clock driver. We're doing that in a separate file, with the main Ethernet driver calling the PTP driver's [de]initialization and interrupt handler functions. Unfortunately, the clock seems tightly coupled with the AVB-DMAC, so when that one leaves the operation mode, we have to unregister the PTP clock... :-( Based on the original patches by Masaru Nagai.

Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically compatible with SuperH Gigabit Ethernet E-MAC. Ethernet AVB has a dedicated direct memory access controller (AVB-DMAC) that is a new design compared to the SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE 802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real- time transfer, and the IEEE 802.1Qat stream reservation protocol. The driver only supports device tree probing, so the binding document is included in this patch. Based on the original patches by Mitsuhiro Kimura.

CAIA Delay-Gradient (CDG) is a TCP congestion control that modifies the TCP sender in order to [1]: o Use the delay gradient as a congestion signal. o Back off with an average probability that is independent of the RTT. o Coexist with flows that use loss-based congestion control, i.e., flows that are unresponsive to the delay signal. o Tolerate packet loss unrelated to congestion. (Disabled by default.) Its FreeBSD implementation was presented for the ICCRG in July 2012; slides are available at http://www.ietf.org/proceedings/84/iccrg.html Running the experiment scenarios in [1] suggests that our implementation achieves more goodput compared with FreeBSD 10.0 senders, although it also causes more queueing delay for a given backoff factor. The loss tolerance heuristic is disabled by default due to safety concerns for its use in the Internet [2, p. 45-46]. We use a variant of the Hybrid Slow start algorithm in tcp_cubic to reduce the probability of slow start overshoot. [1] D.A. Hayes and G. Armitage.

If CONFIG_NET_SWITCHDEV is enabled, but port driver does not implement support for IPv4 FIB add/del ops, don't fail route add/del offload operations. Route adds will not be marked as OFFLOAD. Routes will be installed in the kernel FIB, as usual. This was report/fixed by Florian when testing DSA driver with net-next on devices with L2 offload support but no L3 offload support. What he reported was an initial route installed from DHCP client would fail (route not installed to kernel FIB). This was triggering the setting of ipv4.fib_offload_disabled, which would disable route offloading after the first failure. So subsequent attempts to install the route would succeed. There is follow-on work/discussion to address the handling of route install failures, but for now, let's differentiate between no support and failed support.

As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.
