2019-04-23ARM: ixp4xx: Move IXP4xx QMGR and NPE headersLinus Walleij
This moves the IXP4xx Queue Manager and Network Processing Engine headers out of the <mack/*> include path as that is incompatible with multiplatform. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2019-04-23ARM: ixp4xx: Add device tree boot supportLinus Walleij
This adds a minimal support for booting IXP4xx systems from device tree. We have to add hacks to the QMGR, NPE and notably also ethernet and watchdog drivers so that they don't crash the platform: these drivers are unconditionally starting to grab regions of statically remapped IO space with no concern of the device model or other platforms. We will go in and properly fix these drivers as we go along but for now this hack gets us to a place where we can start working on proper device tree support for these platforms.

2016-10-13net: deprecate eth_change_mtu, remove usageJarod Wilson
With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

2015-06-23drivers/net: remove all references to obsolete Ethernet-HOWTOPaul Gortmaker
This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2015-02-20ethernet/ixp4xx: prevent allmulti from clobbering promiscDerrick Pallas
If both promisc and allmulti are set, promisc should trump allmulti and disable the MAC filter; otherwise, the interface is not really promisc. Previously, this code checked IFF_ALLMULTI prior to and without regard for IFF_PROMISC; if both were set, only multicast and direct unicast traffic would make it through the filter.

2014-04-01net: ptp: move PTP classifier in its own fileDaniel Borkmann
This commit fixes a build error reported by Fengguang, that is triggered when CONFIG_NETWORK_PHY_TIMESTAMPING is not set: ERROR: "ptp_classify_raw" [drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe.ko] undefined! The fix is to introduce its own file for the PTP BPF classifier, so that PTP_1588_CLOCK and/or NETWORK_PHY_TIMESTAMPING can select it independently from each other. IXP4xx driver on ARM needs to select it as well since it does not seem to select PTP_1588_CLOCK or similar that would pull it in automatically. This also allows for hiding all of the internals of the BPF PTP program inside that file, and only exporting relevant API bits to drivers. This patch also adds a kdoc documentation of ptp_classify_raw() API to make it clear that it can return PTP_CLASS_* defines. Also, the BPF program has been translated into bpf_asm code, so that it can be more easily read and altered (extensively documented in [1]). In the kernel tree under tools/net/ we have bpf_asm and bpf_dbg tools, so the commented program can simply be translated via `./bpf_asm -c prog` where prog is a file that contains the commented code. This makes it easily readable/verifiable and when there's a need to change something, jump offsets etc do not need to be replaced manually which can be very error prone. Instead, a newly translated version via bpf_asm can simply replace the old code. I have checked opcode diffs before/after and it's the very same filter.

2014-03-31net: ptp: do not reimplement PTP/BPF classifierDaniel Borkmann
There are currently pch_gbe, cpts, and ixp4xx_eth drivers that open-code and reimplement a BPF classifier for the PTP protocol. Since all of them effectively do the very same thing and load the very same PTP/BPF filter, we can just consolidate that code by introducing ptp_classify_raw() in the time-stamping core framework which can be used in drivers. As drivers get initialized after bootstrapping the core networking subsystem, they can make use of ptp_insns wrapped through ptp_classify_raw(), which allows to simplify and remove PTP classifier setup code in drivers.

2013-01-14net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli
The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.
