ef45c9147f pcnet: Properly handle TX requests during Link Fail 
As long as we have no link and we aren't in internal loopback mode, no
packet must be sent. Instead, LCAR needs to be set in any active TX
descriptor and also CERR in CSR0.

e1c2008af6 pcnet: Add link state support 
Update lnkst on link state changes so that guests can obtain this
information via reading back the LED output pin. Works for Linux but
not for guests that depend on the missing PHY.

488a1a5dfe pcnet: Move BCR defines to header 
This moves BCR defines to the common header and immediately makes use of
them to add BCR_APROMWE, replacing the open-coded write check in
pcnet_aprom_writeb.

fe87aa83c6 pcnet: avoid structure holes spotted by pahole 
Edited report from pahole on amd64 host:
struct PCNetState_st {
...
	uint16_t                   bcr[32];              /*   340    64 */

	/* XXX 4 bytes hole, try to pack */
...
	int                        tx_busy;              /*  4520     4 */

	/* XXX 4 bytes hole, try to pack */

	qemu_irq                   irq;                  /*  4528     8 */
	void                       (*phys_mem_read)(void *, target_phys_addr_t, uint8_t *, int, int); /*  4536     8 */
	/* --- cacheline 71 boundary (4544 bytes) --- */
	void                       (*phys_mem_write)(void *, target_phys_addr_t, uint8_t *, int, int); /*  4544     8 */
	void *                     dma_opaque;           /*  4552     8 */
	int                        looptest;             /*  4560     4 */

	/* size: 4568, cachelines: 72 */
	/* sum members: 4556, holes: 2, sum holes: 8 */
	/* padding: 4 */
	/* last cacheline: 24 bytes */
};	/* definitions: 2 */

Fix by rearranging the structure to avoid padding.

a4c75a21f3 Split out common pcnet code 
The core pcnet emulation code is used by both the PCI "pcnet" device
and the SPARC "lance" device.  Split the common code frm the PCI code so
that that can be configures independantly.
