Subject: [PATCH 5/8] drivers/net/mv643xx_eth.c: Use FIELD_SIZEOF

From: Julia Lawall <julia@...u.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/)
