2009-11-07be2net: Bug fix to send config commands to hardware after netdev_registerAjit Khaparde1-12/+12
Sending config commands to be2 hardware before netdev_register is completed, is sometimes causing the async link notification to arrive even before the driver is ready to handle it. The commands for vlan config and flow control settings can infact wait till be_open. This patch takes care of that. Signed-off-by: Ajit Khaparde <ajitk@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-07be2net: fix to set proper flow control on resumeAjit Khaparde3-4/+14
If be2 goes into suspend after a user changes the flow control settings, we are not programming them back after resume. This patch takes care of it. We now get the flow control settings before going to suspend mode and then apply them during resume. Signed-off-by: Ajit Khaparde <ajitk@serverengines.com> Signed-off-by: David S.

2009-10-07be2net: Bug fix to properly update ethtool tx-checksumming after ethtool -K ↵Ajit Khaparde2-3/+3
<ifname> tx off This is a fix for a bug which was a result of wrong use of checksum offload flag. The status of tx-checksumming was not changed from on to off after a 'ethtool -K <ifname> tx off' operation. Use the proper checksum offload flag NETIF_F_HW_CSUM instead of NETIF_F_IP_CSUM and NETIF_F_IPV6_CSUM. Patch is against net-2.6 tree.

2009-06-29be2net: Fix to avoid a crash seen on PPC with LRO and Jumbo frames.Ajit Khaparde3-16/+35
While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames. With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[]. Now we coalesce the frags from the same physical page into one slot in skb_shinfo(skb)->frags[] and go to the next index when the frag is from different physical page.

2009-06-19be2net: Use MCC queue for cmds that may be called in BH contextSathya Perla1-17/+52
Currenlty multicast_set and promiscuous_config cmds -- that may be called in BH context -- use the blocking MCC mbox to post cmds. An mbox cmd is protected via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable to disable BHs while a blocking mbox cmd is in progress (and take long to finish.) This can lockup a cmd in progress in process context. So, these two cmds in BH context must use the MCC queue to post cmds.

2009-06-09be2net: Remove unnecessary frag list traversing.David S. Miller1-31/+25
This driver does not indicate support for frag lists. Furthermore, even if it did, the code is walking the frag lists incorrectly. The idiom is: for (iter = skb_shinfo(skb)->frag_list; iter; iter = iter->next) but it's doing: for (iter = skb_shinfo(skb)->frag_list; iter; iter = skb_shinfo(iter)->frag_list) which would never work. And this proves that this driver never saw an SKB with active frag lists. So just remove the code altogether and the driver TX path becomes much simpler. Signed-off-by: David S.
