[PATCH 6/8] drivers/net/igb: Use FIELD_SIZEOF

[PATCH 6/8] drivers/net/igb: Use FIELD_SIZEOF

[Julia Lawall]

From: Julia Lawall <julia@diku.dk>

Robert P.J. Day proposed to use the macro FIELD_SIZEOF in replace of code
that matches its definition.

The modification was made using the following semantic patch
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@haskernel@
@@

#include <linux/kernel.h>

@depends on haskernel@
type t;
identifier f;
@@

- (sizeof(((t*)0)->f))
+ FIELD_SIZEOF(t, f)

@depends on haskernel@
type t;
identifier f;
@@

- sizeof(((t*)0)->f)
+ FIELD_SIZEOF(t, f)
// </smpl>

thanks for the (3) patches, I'll make sure they get merged.
