2016-03-02qed: Fix error flow on slowpath startYuval Mintz3-44/+64
In case of problems when initializing the chip, the error flows aren't being properly done. Specifically, it's possible that the chip would be left in a configuration allowing it [internally] to access the host memory, causing fatal problems in the device that would require power cycle to overcome.

2016-03-02qed: Support B0 instead of A0Yuval Mintz2-19/+24
BB_A0 is a development model that is will not reach actual clients. In fact, future firmware would simply fail to initialize such chip. This changes the configuration into B0 instead of A0, and adds a safeguard against the slim chance someone would actually try this with an A0 adapter in which case probe would gracefully fail.

2016-03-02qed: Print additional HW attention infoYuval Mintz2-105/+479
This patch utilizes the attention infrastructure to log additional information that relates only to specific HW blocks. For some of those HW blocks, it also stops automatically disabling the attention generation as the attention is considered benign and thus should only be logged; No fear of it flooding the system.

2016-03-02qed: Print HW attention reasonsYuval Mintz1-107/+1436
Each HW block contains common information about attention reasons, raising a bit for each one of the different sub-reasons that caused it to raise an attention. This patch extends the infrastructure by allowing logging of the various reasons causing the HW blocks to generate an attention.

2016-03-02qed: Add support for HW attentionsYuval Mintz2-40/+357
HW is capable of generating attentnions for a multitude of reasons, but current driver is enabling attention generation only for management firmware [required for link notifications]. This patch enables almost all of the possible reasons for HW attentions, logging the HW block generating the attention and preventing further attentions from that source [to prevent possible attention flood]. It also lays the infrastructure for additional exploration of the various attentions. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-02-22qed: Handle possible race in SB configYuval Mintz1-9/+9
Due to HW design, some of the memories are wide-bus and access to those needs to be sequentialized on a per-HW-block level; Read/write to a given HW-block might break other read/write to wide-bus memory done at ~same time. Status blocks initialization in CAU is done into such a wide-bus memory. This moves the initialization into using DMAE which is guaranteed to be safe to use on such memories.

2016-02-19qed: Lay infrastructure for vlan filtering offloadYuval Mintz1-4/+19
Today, interfaces are working in vlan-promisc mode; But once vlan filtering offloaded would be supported, we'll need a method to control it directly [e.g., when setting device to PROMISC, or when running out of vlan credits].

The problem here is that at the end of the loop we test for if idc->vnic_wait_limit is zero, but since idc->vnic_wait_limit-- is a post-op, it actually ends up set to (u8)-1.

2015-12-07qed: Correct slowpath interrupt schemeSudarsana Kalluru4-52/+55
When using INTa, ISR might be called before device is configured for INTa [E.g., due to other device asserting the shared interrupt line], in which case the ISR would read the SISR registers that shouldn't be read unless HW is already configured for INTa. This might break interrupts later on. There's also an MSI-X issue due to this difference, although it's mostly theoretical. This patch changes the initialization order, calling request_irq() for the slowpath interrupt only after the chip is configured for working in the preferred interrupt mode.

2015-12-07qed: fix handling of concurrent ramrods.Tomer Tayar2-17/+54
Concurrent non-blocking slowpath ramrods can be completed out-of-order on the completion chain. Recycling completed elements, while previously sent elements are still completion pending, can lead to overriding of active elements on the chain. Furthermore, sending pending slowpath ramrods currently lacks the update of the chain element physical pointer. This patch: * Ensures that ramrods are sent to the FW with consecutive echo values. * Handles out-of-order completions by freeing only first successive completed entries. * Updates the chain element physical pointer when copying a pending element into a free element for sending.

2015-11-07net/qlcnic: fix mac address restore in bond mode 5/6Jarod Wilson1-1/+2
The bonding driver saves a copy of slaves' original mac address and then assigns whatever mac as needed to the slave, depending on mode. In at least modes 5 and 6 (balance-tlb, balance-alb), it often ends up being the mac address of another slave. On release from the bond, the original mac address is supposed to get restored via a dev_set_mac_address() call in the bonding driver's __bond_release_one() function, which calls the slave's ndo_set_mac_address function, which for qlcnic, is qlcnic_set_mac(). Now, this function tries to be somewhat intelligent and exit early if you're trying to set the mac address to the same thing that is already set. The problem here is that adapter->mac_addr isn't in sync with netdev->dev_addr. The qlcnic driver still has the original mac stored in adapter->mac_addr, while the bonding driver has updated netdev->dev_addr, so qlcnic thinks we're trying to set the same address it already has. I think the way to go here, since the function updates both netdev and adapter's stored mac addresses, is to check if either of them doesn't match the newly requested mac. Simply checking netdev's value only could result in a similar mismatch and non-update, so look at both.
