547c474fa7 sfc: Remove device ID macros only used once
The SFC9020/SFL9021 device IDs are only used in the device ID table,
where we can just as well use comments.

c2e4e25afc sfc: Use kcalloc instead of kzalloc to allocate array
The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

The semantic patch that makes this change is available
in https://lkml.org/lkml/2011/11/25/107

As soon as skb is pushed to hardware, it can be completed and freed, so
we should not dereference skb anymore.

6eb07caf1a drivers/net: Add moduleparam.h to drivers as required.
These files were using moduleparam infrastructure, but were not
including anything for it -- which is fine when module.h is being
implicitly included in all files, but that is going away.

9e903e0852 net: add skb frag size accessors
To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.

Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.

815c7db5c8 ethtool: Clean up definitions of rule location arrays in RX NFC
Correct the description of ethtool_rxnfc::rule_locs; it is an array
of currently used locations, not all possible valid locations.

Add note that drivers must not use ethtool_rxnfc::rule_locs.

The rule_locs argument to ethtool_ops::get_rxnfc is either NULL or a
pointer to an array of u32, so change the parameter type accordingly.

13225977f5 sfc: Use correct fields of struct ethtool_coalesce
An earlier developer misunderstood the meaning of the 'irq' fields and
the driver did not support the standard fields.  To avoid invalidating
existing user documentation, we report and accept changes through
either the standard or 'irq' fields.  If both are changed at the same
time, we prefer the standard field.

Also explain why we don't currently use the 'max_frames' fields.

a0c4faf548 sfc: Correct reporting and validation of TX interrupt coalescing
The reported TX IRQ moderation is generated in a completely crazy way.
Make it simple and correct.

When channels are shared between RX and TX, TX IRQ moderation must be
the same as RX IRQ moderation, but must be specified as 0!  Allow it
to be either specified as the same, or left at its previous value
in which case it will be quietly overridden.
