Hi Beilei,

thanks for the patches. Since these are coverity fixes, can you please do a V2
with the coverity id's being fixed called out in the commit message. The format
to use is:

	Coverity issue: xxxxx yyyyy ....

just above the fixes line in the patch. [Use "git log" to see examples in other
commits].

Also, for convenience sake for myself and Thomas, can you include just the three
i40e patches in one set - since those go to next-net tree - and submit the
examples fix as a separate standalone patch to go in the main tree.

Thanks,
/Bruce

Fix some open coverity defects.

V2 changes:
 Rework commit log.

[dpdk-dev] [PATCH v2 1/3] i40e: fix log error

[Beilei Xing]

The condition, "(pf->flags | I40E_FLAG_VMDQ)" will always be true,
regardless of the value of the flags operand, because I40E_FLAG_VMDQ
is 4ULL - meaning at least one bit will always be set in the result.
That will cause log error when VMDq is disabled.
Since the original intent behind the condition is to check if VMDq
is enabled, fix the code by changing "|" to "&".

Coverity issue: 13219, 13221

Fixes: 4805ed59e957 ("i40e: enhance mac address operations")

[dpdk-dev] [PATCH v2 2/3] i40e: fix dereference before null check

[Beilei Xing]

Null-checking vsi suggests that it may be null, but it
has be dereferenced before null-checking. So move if
statement to the front of assignment statement.

[dpdk-dev] [PATCH v2 3/3] i40e: fix out-of-bounds access

[Beilei Xing]

When calling i40e_flowtype_to_pctype in
i40e_get_hash_filter_global_config and
i40e_set_hash_filter_global_config, function
i40e_flowtype_to_pctype will be possibly
out-of-bounds accessed, because size of callee's array
is 15. So judge flow type before calling
i40e_flowtype_to_pctype.
Meanwhile do the same change in other functions.

Rather than having the same check done in multiple places, is there a reason
why we can't just put the check once in i40e_flowtype_to_pctype?

Since the return value type of i40e_flowtype_to_pctype is " enum i40e_filter_pctype ", although put the check in i40e_flowtype_to_pctype, we should check return value after every i40e_flowtype_to_pctype calling. I think there's no more improvement.
Besides, check valid flow type is called before i40e_flowtype_to_pctype in some places previously, such as function i40e_hash_filter_inset_select and i40e_fdir_filter_inset_select.

Ok, point taken. If we don't check before the call, then the call itself could
return an error which would then need to be checked anyway.

That's not a reason to keep on putting more checks in other places. It's more
of a reason why the check needs to be centralised. However, from your reasoning
above it doesn't help much, since for these existing cases you'd be just changing
one check for another.
