2015-12-07lan9118: log and ignore access to invalid registers, rather than abortingAndrew Baumann
With this change, access to invalid/unimplemented device registers are logged as a "guest error" rather than aborting qemu with hw_error. This enables drivers for similar devices (e.g. SMSC 9221), by simply ignoring the unimplemented writes. It's also closer to what real hardware does.

2015-12-07lan9118: fix emulation of MAC address loaded bit in E2P_CMD registerAndrew Baumann
There appears to have been a longstanding typo in the implementation of the "MAC address loaded" bit in the E2P_CMD (EEPROM command) register. The code was using 0x10, but the controller spec says it should be bit 8 (0x100). Signed-off-by: Andrew Baumann <Andrew.Baumann@microsoft.com> Signed-off-by: Jason Wang <jasowang@redhat.com>

2015-01-12net: remove all cleanup methods from NIC NetClientInfosPaolo Bonzini
All NICs have a cleanup function that, in most cases, zeroes the pointer to the NICState. In some cases, it frees data belonging to the NIC. However, this function is never called except when exiting from QEMU. It is not necessary to NULL pointers and free data here; the right place to do that would be in the device's unrealize function, after calling qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue devices. This cleanup function gets in the way of making the NetClientStates for the NIC hold an object_ref reference to the object, so get rid of it.

2014-01-27Fix lan9118 buffer length handlingRoy Franz
The 9118 ethernet controller supports transmission of multi-buffer packets with arbitrary byte alignment of the start and end bytes. All writes to the packet fifo are 32 bits, so the controller discards bytes at the beginning and end of each buffer based on the 'Data start offset' and 'Buffer size' of the TX command 'A' format. This patch uses the provided buffer length to limit the bytes transmitted. Previously all the bytes of the last 32-bit word written to the TX fifo were added to the internal transmit buffer structure resulting in more bytes being transmitted than were submitted to the hardware in the command. This resulted in extra bytes being inserted into the middle of multi-buffer packets when the non-final buffers had non-32bit aligned ending addresses.

2014-01-27Fix lan9118 TX "CMD A" handlingRoy Franz
The 9118 ethernet controller supports transmission of multi-buffer packets with arbitrary byte alignment of the start and end bytes. All writes to the packet fifo are 32 bits, so the controller discards bytes at the beginning and end of each buffer based on the 'Data start offset' and 'Buffer size' of the TX command 'A' format. This patch changes the buffer size and offset internal state variables to be updated on every "TX command A" write. Previously they were only updated for the first segment, which resulted incorrect behavior for packets with more than one segment. Each segment of the packet has its own CMD A command, with its own buffer size and start offset. Also update extraction of fields from the CMD A word to use extract32().
