2013-08-20sh_eth: remove 'register_type' field from 'struct sh_eth_plat_data'Sergei Shtylyov10-18/+7
Now that the 'register_type' field of the 'sh_eth' driver's platform data is not used by the driver anymore, it's time to remove it and its initializers from the SH platform code. Also move *enum* declaring values for this field from <linux/sh_eth.h> to the local driver's header file as they're only needed by the driver itself now...

2013-08-20sh_eth: get register layout from 'struct sh_eth_cpu_data'Sergei Shtylyov2-1/+22
The register layout is a SoC characteristic, so it's wrong that it's stored in the otherwise board specific platform data.

2013-08-20SolutionEngine7724: fix Ether supportSergei Shtylyov1-1/+3
The Ether platform data is behind the declaration of 'struct sh_eth_plat_data' as it's lacking the initializers for the 'register_type' and 'phy_interface' fields -- it means they'll be implicitly and wrongly set to SH_ETH_REG_GIGABIT and PHY_INTERFACE_MODE_NA.

The 'sh_eth' driver's probe will crash as the platform code is hopelessly behind the platform data -- it passes PHY ID instead of 'struct sh_eth_plat_data *'. Strangely, both commit d88a3ea6fa4c (SH7619 add ethernet controler support) that added the platform code and commit 71557a37adb5 ([netdrvr] sh_eth: Add SH7619 support) were done in about the same time, yet the latter one added 'struct sh_eth_plat_data' and the platform code didn't ever get updated...

2013-08-20ipv4: raise IP_MAX_MTU to theoretical limitEric Dumazet1-5/+3
As discussed last year [1], there is no compelling reason to limit IPv4 MTU to 0xFFF0, while real limit is 0xFFFF [1] : http://marc.info/?l=linux-netdev&m=135607247609434&w=2 Willem raised this issue again because some of our internal regression tests broke after lo mtu being set to 65536. IP_MTU reports 0xFFF0, and the test attempts to send a RAW datagram of mtu + 1 bytes, expecting the send() to fail, but it does not. Alexey raised interesting points about TCP MSS, that should be addressed in follow-up patches in TCP stack if needed, as someone could also set an odd mtu anyway.

2013-08-20pch_gbe: ethtool cannot change parameters when link is downAnders Larsen1-0/+1
When attempting to change e.g. the advertising mask when the link is down ecmd->speed is -1 causing mii_ethtool_sset() to bail out. This bug bit when connecting to a gigabit switch through a 4-pin (industrial) cable, since link negotiation would not complete (both endpoints claimed to be gigabit-capable, but this is not possible with only 4 pins). Any attempt to fix this by setting autonegation to not offer 1000Mbps failed as the setting would not be accepted while the link was still down... Set ecmd->speed to SPEED_1000 to satisfy mii_ethtool_sset() (the actual value of ecmd->speed doesn't matter as long as it is valid, since a re-negotation is forced afterwards).

Alexander Aring says: ==================== 6lowpan: address uncompression fixes The current implementation to uncompress addresses in a 6lowpan header is completely broken. This patch series fixes the parsing of addresses in a 6lowpan header. It contains a major rewrite of the uncompress address function to parse the address in a correct way. Tested with the ravenusbstick(contiki 6LoWPAN stack) and beaglebone (linux 6LoWPAN Stack) on the other side. The linux side contains all possible addresses for the uncompression cases. Then I type a ping6 for each case and lookup in wireshark and dmesg the correct reconstruction. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-08-206lowpan: lowpan_uncompress_addr with address_modeAlexander Aring2-71/+82
This patch drops the pre and postcount calculation from the lowpan_uncompress_addr function.We use instead a switch/case over address_mode value. The original implementation has several bugs in this function and it was hard to decrypt how it works. To make it maintainable and fix these bugs this patch basically reimplements lowpan_uncompress_addr from scratch. A list of bugs we found in the current implementation: 1) Properly support uncompression of short-address based IPv6 addresses (instead of basically copying garbage) 2) Fix use and uncompression of long-addresses based IPv6 addresses 3) Add missing ff:fe00 in the case of SAM/DAM = 2 and M = 0 Signed-off-by: Alexander Aring <alex.aring@gmail.com> Reviewed-by: Werner Almesberger <werner@almesberger.net> Signed-off-by: David S.

2013-08-206lowpan: Fix fragmentation with link-local compressed addressesDavid Hauweele1-0/+6
When a new 6lowpan fragment is received, a skbuff is allocated for the reassembled packet. However when a 6lowpan packet compresses link-local addresses based on link-layer addresses, the processing function relies on the skb mac control block to find the related link-layer address. This patch copies the control block from the first fragment into the newly allocated skb to keep a trace of the link-layer addresses in case of a link-local compressed address.
