be2net: use PCI MMIO read instead of config read for errors

2015-03-20T17:25:51+00:00

When an EEH error occurs, the device/slot is disconnected. This condition
is more reliably detected (i.e., returns all ones) with an MMIO read rather
than a config read -- especially on power platforms.

Hence, this patch fixes EEH error detection by replacing config reads with
MMIO reads for reading the error registers. The error registers in
Skyhawk-R/BE2/BE3 are accessible both via the config space and the
PCICFG (BAR0) memory space.

be2net: restrict MODIFY_EQ_DELAY cmd to a max of 8 EQs

2015-03-20T17:25:51+00:00

Issuing this cmd for more than 8 EQs does not have the intended effect
even on BEx and Skyhawk-R.

This patch fixes this by issuing this cmd for upto 8 EQs at a time.

be2net: Prevent VFs from enabling VLAN promiscuous mode

2015-03-20T17:25:51+00:00

Currently, a PF does not restrict its VF interface from enabling vlan
promiscuous mode. This breaks vlan isolation when a vlan
(transparent tagging) is configured on a VF.

This patch fixes this problem by disabling the vlan promisc capability
for VFs.

MODULE_DEVICE_TABLE: fix some callsites

2015-02-14T05:21:40+00:00

The patch "module: fix types of device tables aliases" newly requires that
invocations of

MODULE_DEVICE_TABLE(type, name);

come *after* the definition of `name'.  That is reasonable, but some
drivers weren't doing this.  Fix them.

be2net: avoid unncessary swapping of fields in eth_tx_wrb

2015-02-08T06:50:59+00:00

The 32-bit fields of a tx-wrb are little endian. The driver is currently
using be_dws_le_to_cpu() routine to swap (cpu to le) all the fields of
a tx-wrb. So, the rsvd field is also unnecessarily swapped.

This patch fixes this by individually swapping the required fields.
Also, the type of the fields in eth_tx_wrb{} is now changed to __le32
from u32 to avoid sparse warnings.

be2net: process port misconfig async event

2015-02-08T06:50:59+00:00

This patch adds support for processing the port misconfigure async
event generated by the FW. This event is generated typically when an
optical module is incorrectly installed or is faulty.

This patch also moves the port_name field to the adapter struct for
logging the event. As the be_cmd_query_port_name() call is now moved
to be_get_config(), it is modified to use the mailbox instead of MCCQ

be2net: refactor be_set_rx_mode() and be_vid_config() for readability

2015-02-08T06:50:59+00:00

This patch re-factors the filter setting (uc-list, mc-list, promisc, vlan)
code in be_set_rx_mode() and be_vid_config() to make it more readable
and reduce code duplication.
This patch adds a separate field to track the state/mode of filtering,
along with moving all the filtering related fields to one place in be
be_adapter structure.

be2net: remove duplicate code in be_cmd_rx_filter()

2015-02-08T06:50:58+00:00

This patch passes BE_IF_FLAGS_XXX flags to be_cmd_rx_filter() routine
instead of the IFF_XXX flags. Doing this gets rid of the code to convert
the IFF_XXX flags to the BE_IF_FLAGS_XXX used by the FW cmd. The patch
also removes code for setting if_flags_mask that was duplicated for each
filter mode.

be2net: use offset based FW flashing for Skyhawk chip

2015-02-08T06:50:58+00:00

While sending FW update cmds to the FW, the driver specifies the "type"
of each component that needs to be flashed. The FW then picks the offset
in the flash area at which the componnet is to be flashed. This doesn't work
when new components that the current FW doesn't recognize, need to be
flashed. Recent FWs (10.2 and above) support a scheme of FW-update wherein
the "offset" of the component in the flash area can be specified instead
of the "type". This patch uses the "offset" based FW-update mechanism and
only when it fails, it fallsback to the old "type" based update.
