2011-01-13IB/mlx4: Handle protocol field in multicast tableAleksey Senin1-10/+13
The newest device firmware stores IB vs. Ethernet protocol in two bits in members_count field of multicast group table (0: Infiniband, 1: Ethernet). When changing the QP members count for a multicast group, it important not to reset this information. When calling multicast attach first time, the protocol type should be specified. In this patch we always set it IB, but in the future we will handle Ethernet too. When looking for a QP, the protocol type shoud be checked too.

2011-01-12mlx4_{core, ib, en}: Fix driver when sizeof (phys_addr_t) > sizeof (long)Roland Dreier3-5/+6
Some systems have PCI addresses that don't fit in unsigned long (eg some 32-bit PowerPC 440 systems have 36-bit bus addresses). Fix up mlx4 drivers by using phys_addr_t where appropriate, so we don't truncate any PCI resource addresses before ioremapping them. Signed-off-by: Roland Dreier <rolandd@cisco.com>

The kernel warning message added in commit 58d74bb1d9f7 ("mlx4_core: Workaround firmware bug in query dev cap") about mlx4 reporting the wrong number of "blue flame registers" doesn't really help anyone, since the firmware bug is known and fixed and the bug is pretty much harmless to users.

2010-12-02mlx4_core: Workaround firmware bug in query dev capEli Cohen1-0/+4
ConnectX firmware is supposed to report the number blue flame registers per page as log2 of the value. However, due to a firmware bug, it reports actual number. This patch works around this by checking if the number of registers calculated fits within a page. If it does not, we use 8 registers per page.

When searching for a free entry in either mlx4_register_vlan() or mlx4_register_mac(), and there is no free entry, the loop terminates without updating the local variable free thus causing out of array bounds access.

2010-10-25IB/mlx4: Add VLAN support for IBoEEli Cohen3-0/+30
This patch allows IBoE traffic to be encapsulated in 802.1Q tagged VLAN frames. The VLAN tag is encoded in the GID and derived from it by a simple computation. The netdev notifier callback is modified to catch VLAN device addition/removal and the port's GID table is updated to reflect the change, so that for each netdevice there is an entry in the GID table. When the port's GID table is exhausted, GID entries will not be added. Only children of the main interfaces can add to the GID table; if a VLAN interface is added on another VLAN interface (e.g. "vconfig add eth2.6 8"), then that interfaces will not add an entry to the GID table.

2010-10-25mlx4_core: Allow protocol drivers to find corresponding interfacesEli Cohen2-3/+33
Add a mechanism for mlx4 protocol drivers to get a pointer to other drivers's device objects. For this, an exported function, mlx4_get_protocol_dev() is added, which allows a driver to get some other driver's device based on the protocol that the driver implements. Two protocols are added: MLX4_PROTOCOL_IB and MLX4_PROTOCOL_EN. This will be used in mlx4 IBoE support so that mlx4_ib can find the corresponding mlx4_en netdev.

2010-10-21vlan: Don't check for vlan group before vlan_tx_tag_present.Jesse Gross1-2/+2
Many (but not all) drivers check to see whether there is a vlan group configured before using a tag stored in the skb. There's not much point in this check since it just throws away data that should only be present in the expected circumstances. However, it will soon be legal and expected to get a vlan tag when no vlan group is configured, so remove this check from all drivers to avoid dropping the tags.
