2016-10-23net: fec: Call swap_buffer() prior to IP header alignmentFabio Estevam1-3/+3
Commit 3ac72b7b63d5 ("net: fec: align IP header in hardware") breaks networking on mx28. There is an erratum on mx28 (ENGR121613 - ENET big endian mode not compatible with ARM little endian) that requires an additional byte-swap operation to workaround this problem. So call swap_buffer() prior to performing the IP header alignment to restore network functionality on mx28.

If the mac address origin is not dt, you can only safely assign a mac address after "link up" of the device. If the link is off the clocks are disabled and because of issues assigning registers when clocks are off the new mac address cannot be written in .ndo_set_mac_address() on some soc's.

2016-09-27net: fec: align IP header in hardwareEric Nelson1-1/+10
The FEC receive accelerator (RACC) supports shifting the data payload of received packets by 16-bits, which aligns the payload (IP header) on a 4-byte boundary, which is, if not required, at least strongly suggested by the Linux networking layer.

2016-09-10net: fs_enet: don't unmap DMA when packet len is below copybreakChristophe Leroy1-16/+20
When the length of the packet is below the defined copybreak limit, the received packet is copied into a newly allocated skb in order to reuse the skb. This is only interesting if it allow us to avoid a new DMA mapping. We shall therefore not DMA unmap and remap the skb->data. Instead, we invalidate the cache with dma_sync_single_for_cpu() once the received data has been copied into the new skb. The following measures have been obtained on a mpc885 running at 132Mhz. Measurement is done using the timebase with packets sent to the target with 'ping -s 1' (packet len is 60): * Without this patch: 182 TB ticks * With this patch: 143 TB ticks As a comparison, if we set the copybreak limit to 0, then we get 148 TB ticks. It means that without this patch, duration is even worse when copying received data to a new skb instead of allocating a new skb for next packet to be received Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: David S.

2016-09-10net: fs_enet: merge NAPI RX and NAPI TXChristophe Leroy5-295/+160
Initially, a NAPI TX routine has been implemented separately from NAPI RX, as done on the freescale/gianfar driver. By merging NAPI RX and NAPI TX, we reduce the amount of TX completion interrupts. Handling of the budget in association with TX interrupts is based on indications provided at https://wiki.linuxfoundation.org/networking/napi We never proceed more than the complete TX ring on a single run. At the same time, we fix an issue in the handling of fep->tx_free: It is only when fep->tx_free goes up to MAX_SKB_FRAGS that we need to wake up the queue.

2016-08-23gianfar: fix size of scatter-gathered framesZefir Kurtisi1-6/+14
The current scatter-gather logic in gianfar is flawed, since it does not consider the eTSEC's RxBD 'Data Length' field is context depening: for the last fragment it contains the full frame size, while fragments contain the fragment size, which equals the value written to register MRBLR. This causes data corruption as soon as the hardware starts to fragment receiving frames. As a result, the size of fragmented frames is increased by (nr_frags - 1) * MRBLR We first noticed this issue working with DSA, where an ICMP request sized 1472 bytes causes the scatter-gather logic to kick in. The full Ethernet frame (1518) gets increased by DSA (4), GMAC_FCB_LEN (8), and FSL_GIANFAR_DEV_HAS_TIMER (priv->padding=8) to a total of 1538 octets, which is fragmented by the hardware and reconstructed by the driver to a 3074 octet frame. This patch fixes the problem by adjusting the size of the last fragment. It was tested by setting MRBLR to different multiples of 64, proving correct scatter-gather operation on frames with up to 9000 octets in size.

2016-08-23gianfar: prevent fragmentation in DSA environmentsZefir Kurtisi1-1/+2
The eTSEC register MRBLR defines the maximum space in the RX buffers and is set to 1536 by gianfar. This reasonably covers the common use case where the MTU is kept at default 1500. In that case, the largest Ethernet frame size of 1518 plus an optional GMAC_FCB_LEN of 8, and an additional padding of 8 to handle FSL_GIANFAR_DEV_HAS_TIMER totals to 1534 and nicely fit within the chosen MRBLR. Alas, if the eTSEC is attached to a DSA enabled switch, the (E)DSA header extension (4 or 8 bytes) causes every maximum sized frame to be fragmented by the hardware. This patch increases the maximum RX buffer size by 8 and rounds up to the next multiple of 64, which the hardware's defines as RX buffer granularity.

2016-05-27remove lots of IS_ERR_VALUE abusesArnd Bergmann3-5/+5
Most users of IS_ERR_VALUE() in the kernel are wrong, as they pass an 'int' into a function that takes an 'unsigned long' argument. This happens to work because the type is sign-extended on 64-bit architectures before it gets converted into an unsigned type. However, anything that passes an 'unsigned short' or 'unsigned int' argument into IS_ERR_VALUE() is guaranteed to be broken, as are 8-bit integers and types that are wider than 'unsigned long'. Andrzej Hajda has already fixed a lot of the worst abusers that were causing actual bugs, but it would be nice to prevent any users that are not passing 'unsigned long' arguments. This patch changes all users of IS_ERR_VALUE() that I could find on 32-bit ARM randconfig builds and x86 allmodconfig. For the moment, this doesn't change the definition of IS_ERR_VALUE() because there are probably still architecture specific users elsewhere. Almost all the warnings I got are for files that are better off using 'if (err)' or 'if (err < 0)'. The only legitimate user I could find that we get a warning for is the (32-bit only) freescale fman driver, so I did not remove the IS_ERR_VALUE() there but changed the type to 'unsigned long'. For 9pfs, I just worked around one user whose calling conventions are so obscure that I did not dare change the behavior. I was using this definition for testing: #define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \ unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO)) which ends up making all 16-bit or wider types work correctly with the most plausible interpretation of what IS_ERR_VALUE() was supposed to return according to its users, but also causes a compile-time warning for any users that do not pass an 'unsigned long' argument. I suggested this approach earlier this year, but back then we ended up deciding to just fix the users that are obviously broken. After the initial warning that caused me to get involved in the discussion (fs/gfs2/dir.c) showed up again in the mainline kernel, Linus asked me to send the whole thing again.

2016-05-16net: ethernet: fec-mpc52xx: use phy_ethtool_{get|set}_link_ksettingsPhilippe Reynes1-24/+2
There are two generics functions phy_ethtool_{get|set}_link_ksettings, so we can use them instead of defining the same code in the driver. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-16net: ethernet: fec-mpc52xx: use phydev from struct net_devicePhilippe Reynes1-23/+20
The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phydev in the private structure, and update the driver to use the one contained in struct net_device.
