[PATCH net 0/2] bnxt_en: 2 bug fixes.

[Michael Chan]

The first one fixes a bug to properly identify some recently added HyperV
device IDs.  The second one fixes device context memory set up on systems
with 64K page size.

Please queue these for -stable as well.  Thanks.

Andy Gospodarek (1):
  bnxt_en: Include new P5 HV definition in VF check.

[PATCH net 1/2] bnxt_en: Include new P5 HV definition in VF check.

[Michael Chan]

From: Andy Gospodarek <gospo@broadcom.com>

Otherwise, some of the recently added HyperV VF IDs would not be
recognized as VF devices and they would not initialize properly.

[PATCH net 2/2] bnxt_en: Fix context memory setup for 64K page size.

[Michael Chan]

There was a typo in the code that checks for 64K BNXT_PAGE_SHIFT in
bnxt_hwrm_set_pg_attr().  Fix it and make the code more understandable
with a new macro BNXT_SET_CTX_PAGE_ATTR().
