* include/grub/net.h (grub_net_card): New member txbufsize. 

* include/grub/ieee1275/ieee1275.h (grub_ieee1275_flag): New enum values
	GRUB_IEEE1275_FLAG_NO_OFNET_SUFFIX and
	GRUB_IEEE1275_FLAG_VIRT_TO_REAL_BROKEN.
	* grub-core/net/drivers/efi/efinet.c (grub_efinet_findcards): Use
	txbufsize.
	* grub-core/kern/ieee1275/cmain.c (grub_ieee1275_find_options): Use
	compatible property to check for macs. Set
	GRUB_IEEE1275_FLAG_NO_OFNET_SUFFIX and
	GRUB_IEEE1275_FLAG_VIRT_TO_REAL_BROKEN on macs.
	* grub-core/net/drivers/ieee1275/ofnet.c (card_open): Don't add suffix
	if GRUB_IEEE1275_FLAG_NO_OFNET_SUFFIX is set.
	(send_card_buffer): Use txbuf.
	(grub_ofnet_findcards): Allocate txbuf. Simplify code flow and move
	nested function out of the parent while on it.
