[PATCH v3 01/10] net/bnx2x: set cache line based on build configuration

[PATCH v3 01/10] net/bnx2x: set cache line based on build configuration

[Chas Williams]

Correctly hint the cache line size.  Remove unused macros associated
with the cache line size.

[PATCH v3 02/10] net/bnx2x: remove unused preprocessor symbols and code

[Chas Williams]

ELINK_INCLUDE_EMUL and ELINK_INCLUDE_FPGA are never defined.  Remove them
along with enumeration constants dependent on their inclusion.

[PATCH v3 03/10] net/bnx2x: remove delay during device startup

[Chas Williams]

This 2.5s delay doesn't seem to serve any purpose other than a being a
pause after logging the device configuration.

[PATCH v3 05/10] net/bnx2x: restrict RX mask flags sent to the PF

[Chas Williams]

Don't use bnx2x_fill_accept_flags() to fill the RX mask in the VF
since the PF only handles a subset of the existing flags.  now,
bnx2x_fill_accept_flags() can be static.

[PATCH v3 08/10] net/bnx2x: check return codes during VF mailbox operation

[Chas Williams]

Refactor bnx2x_do_req4pf() to be easier to read and return errors when
the transaction fails -- Previously, it could succeed when the control
channel was down.

Fixes: 540a211084a7 ("bnx2x: driver core")

[PATCH v3 09/10] net/bnx2x: don't return structs

[Chas Williams]

bnx2x_loop_obtain_resources() returns a struct.  This routine either
succeeds or fails -- We don't need a struct for that.

Fixes: 540a211084a7 ("bnx2x: driver core")

[PATCH v3 10/10] net/bnx2x: merge debug register operations into headers

[Chas Williams]

The register read/writes should just be static inline instead of
alternately defined as routines or macros depending on the status of
debugging.

Fix bnx2x_reg_read32() returning 0 during debug unaligned reads.

Fixes: b5bf7719221d ("bnx2x: driver support routines")
