[SCSI] fcoe: Move fcoe_debug_logging from fcoe.h to fcoe.c

2012-01-16T08:46:31+00:00

Move the definition of the global variable fcoe_debug_logging
from fcoe.h to fcoe.c. Avoid that sparse complains about missing
declarations for local functions or variables by declaring these
static.

[SCSI] fcoe: fix regression on offload em matching function for initiator/target

2012-01-16T08:44:28+00:00

This is a regression introduced by commit
1ff9918b625457ce20d450d00f9ed0a12ba191b7 The else statement here is breaking
the initiator logic of allocating xid from the offloaded em xid pool for READ
I/O only to use DDP, as shown by the snippet of trace below, where the WRITE
is using xid 0x5 from the offloaded em xid pool:

Protocol VID Len S_ID        D_ID     OX_ID  RX_ID  Summary
..
*FCP     228 96  0b.08.01 -> 01.0f.00 0x0005 0xffff SCSI: Write(10) LUN: 0x00
 FCP     228 76  01.0f.00 -> 0b.08.01 0x0005 0x828d XFER_RDY
...

The bug is in the else statement, for both initiator and target, the
new command will have FC frame header bit 23 (FC_FC_EX_CTX) cleared as it was
originated from the initiator. Also, this is assuming the frame header is
already filled up, which is only true for target since for initiator, this is a
new frame and oem_match gets called when em tries get xid for this i/o before
it is filled up and sent out.

The fix is to check if there is a fc_fcp_pkt associated w/ this frame from
fr_fsp(fp), since fr_fsp(fp) is NULL for tcm_fc target and non-I/O frame in
initiator. This should also return true for target only if it is an
FC_RCTL_DD_UNSOL_CMD and rx_id is not allocated.

[SCSI] fcoe: remove double check if skb is nonlinear

2012-01-10T23:01:23+00:00

skb_linearize already has a check for skb_is_nonlinear,
there is no need to duplicate the check in fcoe.c. This
patch simply removes the unnecessary check and calls
skb_linearize unconditionally.

[SCSI] fcoe: fix fcoe in a DCB environment by adding DCB notifiers to set skb priority

2011-12-15T07:02:07+00:00

Use DCB notifiers to set the skb priority to allow packets
to be steered and tagged correctly over DCB enabled drivers
that setup traffic classes.

This allows queue_mapping() routines to be removed in these
drivers that were previously inspecting the ethertype of
every skb to mark FCoE/FIP frames.

[SCSI] libfc: improve flogi retries to avoid lport stuck

2011-10-31T09:27:43+00:00

Adds more cases to do flogi retry, now also retry
on getting bad response due to either no ELS response
or flogi response payload length not large enough.
In those cases flogi was not retried and that
was leaving lport offline.

net: add skb frag size accessors

2011-10-19T07:10:46+00:00

To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.

Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.
