* pch_gbe: fix ip_summed checksum reporting on rxVeaceslav Falico2013-04-051-2/+2
| | | | | | | | | | | | | [ Upstream commit 76a0e68129d7d24eb995a6871ab47081bbfa0acc ] skb->ip_summed should be CHECKSUM_UNNECESSARY when the driver reports that checksums were correct and CHECKSUM_NONE in any other case. They're currently placed vice versa, which breaks the forwarding scenario. Fix it by placing them as described above. Signed-off-by: Veaceslav Falico <vfalico@redhat.com> Signed-off-by: David S.

* pch_gbe: Do not abort probe on bad MACDarren Hart2012-05-211-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 2b53d07891630dead46d65c8f896955fd3ae0302 upstream. If the MAC is invalid or not implemented, do not abort the probe. Issue a warning and prevent bringing the interface up until a MAC is set manually (via ifconfig $IFACE hw ether $MAC). Tested on two platforms, one with a valid MAC, the other without a MAC. The real MAC is used if present, the interface fails to come up until the MAC is set on the other. They successfully get an IP over DHCP and pass a simple ping and login over ssh test. This is meant to allow the Inforce SYS940X development board: http://www.inforcecomputing.com/SYS940X_ECX.html (and others suffering from a missing MAC) to work with the mainline kernel. Without this patch, the probe will fail and the interface will not be created, preventing the user from configuring the MAC manually. This does not make any attempt to address a missing or invalid MAC for the pch_phub driver.

* | ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny2011-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.

* | ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny2011-04-292-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline. All drivers visible to make allyesconfig under x86_64 have been updated. Signed-off-by: David Decotigny <decot@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* pch_gbe: Fix the MAC Address load issue.Toshiharu Okada2011-02-142-1/+8
| | | | | | | | | | | | | | | | | | With the specification of hardware, the processing at the time of driver starting was modified. This device write automatically the MAC address read from serial ROM into a MAC Adress1A/1B register at the time of power on reset. However, when stable clock is not supplied, the writing of MAC Adress1A/1B register may not be completed. In this case, it is necessary to load MAC address to MAC Address1A/1B register by the MAC Address1 load register. This patch always does the above processing, in order not to be dependent on system environment. Signed-off-by: Toshiharu Okada <toshiharu-linux@dsn.okisemi.com> Signed-off-by: David S.
