2007-05-03[BNX2]: Fix TSO problem with small MSS.Michael Chan
Remove the check for skb->len greater than MTU when doing TSO. When the destination has a smaller MSS than the source, a TSO packet may be smaller than the MTU at the source and we still need to process it as a TSO packet. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com> for reporting the problem. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-05-03[BNX2]: Add 1-shot MSI handler for 5709.Michael Chan
The 5709 supports the one-shot MSI handler similar to some of the tg3 chips. In this mode, the MSI disables itself automatically until it is re-enabled at the end of NAPI poll. Put the request_irq/free_irq logic in common procedures. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-05-03[BNX2]: Add indirect spinlock.Michael Chan
The indirect register access method will be used by more than one caller in BH context (NAPI poll and timer), so a spinlock is required. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-05-03[BNX2]: Put MII register offsets in the bnx2 struct.Michael Chan

2007-05-03[BNX2]: Fix race conditions when calling register_netdev().Michael Chan
Hot-plug scripts can call bnx2_open() as soon as register_netdev() is called in bnx2_init_one(). We need to call pci_set_drvdata() and setup everything before calling register_netdev(). netif_carrier_off() also needs to be moved to bnx2_open() to avoid race conditions with the irq.

2007-05-03[BNX2]: Add 40-bit DMA workaround for 5708.Michael Chan
The internal PCIE-to-PCIX bridge of the 5708 has the same 40-bit DMA limitation as some of the tg3 chips. Set dma_mask and persistent DMA mask to 40-bit to workaround. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-25[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}Arnaldo Carvalho de Melo
To clearly state the intent of copying from linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2007-04-25[TCP]: Introduce tcp_hdrlen() and tcp_optlen()Arnaldo Carvalho de Melo
The ip_hdrlen() buddy, created to reduce the number of skb->h.th-> uses and to avoid the longer, open coded equivalent. Ditched a no-op in bnx2 in the process. I wonder if we should have a BUG_ON(skb->h.th->doff < 5) in tcp_optlen()... Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-25[IP]: Introduce ip_hdrlen()Arnaldo Carvalho de Melo
For the common sequence "skb->nh.iph->ihl * 4", removing a good number of open coded skb->nh.iph uses, now to go after the rest... Just out of curiosity, here are the idioms found to get the same result: skb->nh.iph->ihl << 2 skb->nh.iph->ihl<<2 skb->nh.iph->ihl * 4 skb->nh.iph->ihl*4 (skb->nh.iph)->ihl * sizeof(u32) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

2007-04-02[BNX2]: Fix nvram write logic.Michael Chan
The nvram dword alignment logic was broken when writing less than 4 bytes on a non-aligned offset. It was missing logic to round the length to 4 bytes. The page erase code is also moved so that it is only called when using non-buffered flash for better code clarity. Update version to 1.5.7.

2007-03-28[BNX2]: Fix link interrupt problem.Michael Chan
bnx2_has_work()'s logic is flawed and can cause the driver to miss a link event. The fix is to compare the status block's attn_bits and attn_bits_ack to determine if there is a link event.

2007-03-02[VLAN]: Avoid a 4-order allocation.Dan Aloni
This patch splits the vlan_group struct into a multi-allocated struct. On x86_64, the size of the original struct is a little more than 32KB, causing a 4-order allocation, which is prune to problems caused by buddy-system external fragmentation conditions. I couldn't just use vmalloc() because vfree() cannot be called in the softirq context of the RCU callback.

2007-02-07MSI: Replace pci_msi_quirk with calls to pci_no_msi()Michael Ellerman
I don't see any reason why we need pci_msi_quirk, quirk code can just call pci_no_msi() instead. Remove the check of pci_msi_quirk in msi_init(). This is safe as all calls to msi_init() are protected by calls to pci_msi_supported(), which checks pci_msi_enable, which is disabled by pci_no_msi(). The pci_disable_msi routines didn't check pci_msi_quirk, only pci_msi_enable, but as far as I can see that was a bug not a feature.

2007-01-25[BNX2]: Fix 2nd port's MAC address.Michael Chan
On the 5709, we need to add the proper offset to calculate the shared memory base address of the 2nd port correctly.

2006-12-17[BNX2]: Fix panic in bnx2_tx_int().Michael Chan
There was an off-by-one bug in bnx2_tx_avail(). If the tx ring is completely full, the producer and consumer indices may be apart by 256 even though the ring size is only 255. One entry in the ring is unused and must be properly accounted for when calculating the number of available entries. The bug caused the tx ring entries to be reused by mistake, overwriting active entries, and ultimately causing it to crash. This bug rarely occurs because the tx ring is rarely completely full. We always stop when there is less than MAX_SKB_FRAGS entries available in the ring.
