The free() and g_free() functions both happily accept NULL on any platform QEMU builds on.

ne2000_receive already checks the same conditions and drops the packet if it's not ready, removing the .can_receive callback avoids the necessity to add explicit flushes when the conditions turn true (which is required by the new semantics of .can_receive since 6e99c63 "net/socket: Drop net_socket_can_send").

2015-09-02rtl8139: Do not consume the packet during overflow in standard mode.Vladislav Yasevich
When operation in standard mode, we currently return the size of packet during buffer overflow. This consumes the overflow packet.

2015-09-02rtl8139: Fix receive buffer overflow checkVladislav Yasevich
rtl8139_do_receive() tries to check for the overflow condition by making sure that packet_size + 8 does not exceed the available buffer space. The issue here is that RxBuffAddr, used to calculate available buffer space, is aligned to a a 4 byte boundry after every update. So it is possible that every packet ends up being slightly padded when written to the receive buffer. This padding is not taken into account when checking for overflow and we may end up missing the overflow condition can causing buffer overwrite. This patch takes alignment into consideration when checking for overflow condition.

2015-07-27axienet: Flush queued packets when rx is doneFam Zheng
eth_can_rx checks s->rxsize and returns false if it is non-zero. Because of the .can_receive semantics change, this will make the incoming queue disabled by peer, until it is explicitly flushed. So we should flush it when s->rxsize is becoming zero. Squash eth_can_rx semantics into etx_rx and drop .can_receive() callback, also add flush when rx buffer becomes available again after a packet gets queued. The other conditions, "!axienet_rx_resetting(s) && axienet_rx_enabled(s)" are OK because enet_write already calls qemu_flush_queued_packets when the register bits are changed.

2015-07-20net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packetsDana Rubin
Convert partially summed packets to be fully checksummed. In case csum offloaded packet, vmxnet3 implementation always passes an RxCompDesc with the "Checksum calculated and found correct" notification to the OS. This emulates the observed ESXi behavior. Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and place a fully computed checksum into the tcp/udp header. Otherwise, the OS driver will receive a checksum-correct indication but with the actual tcp/udp checksum field having just the pseudo header csum value. If host OS performs forwarding, it will forward an incorrectly checksummed packet.
