[dpdk-dev] [PATCH] examples/ethtool: include case for 64-bit registers

From: Zyta Szpak <zyta.szpak at semihalf.com>
rte_eth_dev_get_reg_length and rte_eth_dev_get_reg callbacks
do not provide register size to the app in any way. Example assuming
they are 32-bit wide always allocates not enough memory if the
registers are 64-bit wide. It results in memory corruption.
This commit is a quick fix to make enough room for 64-bit
register values when this returned value is given to malloc.
