2017-07-30net: fec: Allow reception of frames bigger than 1522 bytesAndrew Lunn
The FEC Receive Control Register has a 14 bit field indicating the longest frame that may be received. It is being set to 1522. Frames longer than this are discarded, but counted as being in error. When using DSA, frames from the switch has an additional header, either 4 or 8 bytes if a Marvell switch is used. Thus a full MTU frame of 1522 bytes received by the switch on a port becomes 1530 bytes when passed to the host via the FEC interface. Change the maximum receive size to 2048 - 64, where 64 is the maximum rx_alignment applied on the receive buffer for AVB capable FEC cores. Use this value also for the maximum receive buffer size. The driver is already allocating a receive SKB of 2048 bytes, so this change should not have any significant effects. Tested on imx51, imx6, vf610.

Couple conflicts resolved here: 1) In the MACB driver, a bug fix to properly initialize the RX tail pointer properly overlapped with some changes to support variable sized rings. 2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix overlapping with a reorganization of the driver to support ACPI, OF, as well as PCI variants of the chip. 3) In 'net' we had several probe error path bug fixes to the stmmac driver, meanwhile a lot of this code was cleaned up and reorganized in 'net-next'. 4) The cls_flower classifier obtained a helper function in 'net-next' called __fl_delete() and this overlapped with Daniel Borkamann's bug fix to use RCU for object destruction in 'net'. It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>

Execution 'ethtool -S' on fec device that is down causes OOPS on Vybrid board: Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0898200 pgd = ddecc000 [e0898200] *pgd=9e406811, *pte=400d1653, *ppte=400d1453 Internal error: : 1008 [#1] SMP ARM ... Reason of OOPS is that fec_enet_get_ethtool_stats() accesses fec registers while IPG clock is stopped by PM. Fix that by caching statistics in fec_enet_private. Cache is initialized at device probe time, and updated at statistics request time if device is up, and also just before turning device off on down path. Additional locking is not needed, since cached statistics is accessed either before device is registered, or under rtnl_lock().

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.

2016-05-04net: fec: only clear a queue's work bit if the queue was emptiedUwe Kleine-König
In the receive path a queue's work bit was cleared unconditionally even if fec_enet_rx_queue only read out a part of the available packets from the hardware. This resulted in not reading any packets in the next napi turn and so packets were delayed or lost. The obvious fix is to only clear a queue's bit when the queue was emptied.

2016-03-31fec: Do not access unexisting register in ColdfireFabio Estevam
Commit 55cd48c821de ("net: fec: stop the "rcv is not +last, " error messages") introduces a write to a register that does not exist in Coldfire. Move the FEC_FTRL register access inside the FEC_QUIRK_HAS_RACC 'if' block, so that we guarantee it will not be used on Coldfire CPUs.

2016-03-06net: fec: Rename "phy-reset-active-low" propertyBernhard Walle
is actually "active high". Thanks for Troy Kisky for pointing that out. Since the patch is in linux-next, this patch is incremental and doesn't replace the original patch.
