| | | | | | | | | | | | parsing code in TSO path as the controller requires VLAN hardware tagging to make TSO work over VLANs. While parsing the mbuf in TSO patch, always perform check for writable mbuf as bce(4) have to reset IP length and IP checksum field of IP header and make sure to ensure contiguous buffer before accessing IP/TCP headers.

* The BCE chips appear to have an undocumented requirement that RX frames bescottl2008-05-081-0/+8
| | | | | | | | | | | | aligned on an 8 byte boundary. Prior to rev 1.36 this wasn't a problem because mbuf clusters tend be naturally aligned. The switch to using split buffers with the first buffer being the embedded data area of the mbuf has broken this assumption, at least on i386, causing a complete failure of RX functionality. Fix this for now by using a full cluster for the first RX buffer. A more sophisticated approach could be done with the old buffer scheme to realign the m_data pointer with m_adj(), but I'm also not clear on performance benefits of this old scheme or the performance implications of adding an m_adj() call to every allocation.

Modified BCE_PRINTF macro to automatically fill-in the sc pointer. Fixed a kernel panic when the driver was loaded as a module from the command-line because the MII bus pointer was null (i.e. the MII bus hadn't been enumerated yet). Added fix proposed by Vladimir Ivanov <wawa@yandex-team.ru> to prevent driver state corruption when releasing the lock during the ISR in bce_rx_intr() to send packets up the stack. Added new TX chain and register read sysctl interfaces for debugging. Cleaned up formatting for various other debug routines. Added a new statistic maintained by firmware which tracks the number of received packets dropped because no receive buffers are available.
