[dpdk-dev] [PATCH 0/3] previous patches about "shared code"/"base drivers"

[Thomas Monjalon]

There were discussions about how to fix/workaround bugs in Intel code which
we don't want to modify. And it raised wording issue to clarify things.
I modify my patch and accept others. So I resend them in order to have a
final acknowledgement.

Please comment and/or acknowledge.
Thanks

[dpdk-dev] [PATCH 1/3] i40e: explicit shared code naming as base driver

[Thomas Monjalon]

The PMD is built on top of the base driver which is provided by Intel
and shouldn't be modified to allow easy batch upgrade from Intel.

The base driver is a "shared code" between many projects. But in DPDK,
the "base driver" naming makes more sense.

[dpdk-dev] [PATCH 2/3] i40e/base: ignore warning

[Thomas Monjalon]

From: "Chen Jing D(Mark)" <jing.d.chen@intel.com>

There is a warning in base driver (shared code) on 32-bits RHEL6.3/6.5:
	lib/librte_pmd_i40e/i40e/i40e_lan_hmc.c:917:
	error: integer constant is too large for ‘long’ type

As we don't modify base driver, this warning must be ignored.

[dpdk-dev] [PATCH 3/3] ixgbe: rework fix of media type for bypass device

[Thomas Monjalon]

From: Pablo de Lara <pablo.de.lara.guarch@intel.com>

This was previously solved in commit 60a70d4e042350ca
(fix link status interrupt of bypass device),
but this alternative fix reverts the previous one and solves the
same issue without modifying the base driver (also named "shared code").

I don't object the name change. But I don't see anything good. As some of the API indicates (i40e_init_shared_code), we can call it shared code as what we've done in old PMD drivers. 
BTW, won't this patch overwrite previous one that fix GCC 32bits warning?

My bad. Please ignore " BTW, won't this patch overwrite previous one that fix GCC 32bits warning?"

I've done same kind of minor modifications to e1000 and ixgbe:
	http://dpdk.org/browse/dpdk/commit/?id=2c8e687c549f08522ee

All 3 patches are applied for version 1.7.0.

Thanks
