2012-12-07cnic, bnx2x, bnx2: Simplify cnic probing.Michael Chan1-12/+9
Instead of using symbol_get(), cnic can now directly call the cnic_probe functions in struct bnx2x and struct bnx2. symbol_get() is not reliable as it fails when the module is still initializing. Signed-off-by: Michael Chan <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2012-12-05cnic: Fix rare race condition during iSCSI disconnect.Eddie Wai1-2/+11
If the initiator and target try to close the connection at about the same time, there is a race condition in the termination sequence for bnx2x. Fix the problem by waiting for the remote termination to complete before deleting the Connection ID. This will prevent the firmware assert. Update version to 2.5.15.

2012-10-01bnx2x,cnic: use FW 7.8.2Yuval Mintz1-2/+10
This patch moves the bnx2x and cnic drivers into using FW 7.8.2 which was recently submitted into the linux-firmware tree. A short summary of minor bugs fixed by this FW: 1. In switch dependent mode, fix several issues regarding inner vlan vs. DCB priorities. 2. iSCSI - not all packets were completed on a forward channel. 3. DCB - fixed for 4-port devices. 4. Fixed false parity reported in CAM memories when operating near -5% on the 1.0V core supply. 5. ETS default settings are set to fairness between traffic classes (rather than strict priority), and uses the same chip receive buffer configuration for both PFC and pause. For a complete list of fixes made by this FW, see commit 236367db in the linux-firmware git repository.

2012-07-09drivers/net/ethernet/broadcom/cnic.c: remove invalid reference to list ↵Julia Lawall1-1/+2
iterator variable If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. There does not seem to be a meaningful value to provide to netdev_warn. Replace with pr_warn, since pr_err is used elsewhere.

2012-06-27cnic: Fix occasional NULL pointer dereference during reboot.Michael Chan1-2/+7
We register with bnx2x before we allocate ctx_tbl structure, so it is possible for bnx2x to call cnic_ctl before the structure is allocated. This can sometimes cause NULL pointer dereference of cp->ctx_tbl. We fix this by adding simple checking for valid state before proceeding. The cnic_ctl call is RCU protected so we don't have to deal with race conditions. Because of the additional checking, we need to finish the shutdown before clearing the CNIC_UP flag.

2012-06-06ethernet: Remove casts to same typeJoe Perches1-6/+6
Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p A function in atl1e_main.c was passed a const pointer when it actually modified elements of the structure. Change the argument to a non-const pointer. A function in stmmac needed a __force to avoid a sparse warning. Added it. Signed-off-by: Joe Perches <[email protected]> Signed-off-by: David S.

2012-01-05cnic: Improve error recovery on bnx2x devicesMichael Chan1-5/+69
When a bnx2x device encounters parity errors, it will not respond to all SPQ messages. As a result, the shutdown sequence before reset can take a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout of all such messages. To improve this scenario, when bnx2x returns error on the SPQ, we'll send an immediate response to the ulp drivers to avoid such lengthy timeouts. Adjust the return code of relevant functions to return error only if the message cannot be sent on the SPQ so that we'll generate an error completion to the ulp drivers.
