2014-07-29bfa: Use pci_enable_msix_exact() instead of pci_enable_msix()Alexander Gordeev1-14/+6
As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.

2014-07-25bfa: Fix undefined bit shift on big-endian architectures with 32-bit DMA addressBen Hutchings1-1/+1
bfa_swap_words() shifts its argument (assumed to be 64-bit) by 32 bits each way.

2014-05-19bfa: allocate memory with GFP_ATOMIC in spinlock contextAlexey Khoroshilov1-1/+1
bfa_fcb_pbc_vport_create() is called only from bfa_fcs_pbc_vport_init(), that is called only from bfad_drv_start() with bfad_lock spinlock held.

This patch includes change to enable firmware patch simplication feature. This feature is targeted to address the requirement to have independent patch release for firmware. Prior to 3.2.3, releasing a patch fix for firmware requires changes to bfa, to use new firmware images. But with these changes, if the new firmware is flashed on to the HBA with brocade adapter management utilites, driver uses the new firmware after checking the patch release byte in the firmware version.

Bfa driver crash is observed while pushing the firmware on to chinook quad port card due to uninitialized bfi_image_ct2 access which gets initialized only for CT2 ASIC based cards after request_firmware(). For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting initialized as there is no check for chinook PCI device ID before request_firmware and instead bfi_image_cb is initialized as it is the default case for card type check.

D-Port is a new port type created with the intention of running link level diagnostic tests like loopback, traffic test. In static D-port mode, user configures the port to D-port mode and starts the test, but in dynamic D-port, once the Brocade switch port is configured to D-port, it will reject the regular FLOGI from HBA with reason that it is in D-port mode.
