2) Centralize and simplify TCP RTT measurement handling in order to

Forcing uninitialized state allows us to upgrade and reinitialize the adapter.
FW_VERSION_T4 = 1.4.0.0
FW_VERSION_T5 = 0.0.0.0
At this point driver supports above and greater than above version of firmware.
If it doesn't find the required firmware version than it forces the adapter to
be reinitialized as shown below.
1) If FW_ON_ADAPTER < FW_VERSION and we're the MASTER_PF force uninitialized
state and a FW upgrade if available.
- If FW_ON_ADAPTER < /lib/firmware/cxgb4/t*fw.bin we will update the
adapters FW.
- If FW_ON_ADAPTER >= /lib/firmware/cxgb4/t*fw.bin don't upgrade FW.
- If upgrade_fw() fails force reinitialization of the adapter anyways,
it might still work.
Either way forcing the uninitialized state allows cxgb4 reinitialize FW.
2) If FW_ON_ADAPTER >= FW_VERSION driver follows normal path.

Newer firmware can post CPL_SGE_EGR_UPDATE message encapsulated in a
CPL_FW4_MSG as follows
flit0 rss_header (if DropRSS == 0 in IQ context)
flit1 CPL_FW4_MSG cpl
flit2 rss_header w/opcode CPL_SGE_EGR_UPDATE
flit3 CPL_SGE_EGR_UPDATE cpl
So FW4_MSG CPLs with a newly created type of FW_TYPE_RSSCPL have the
CPL_SGE_EGR_UPDATE CPL message in flit 2 of the FW4_MSG. Firmware can still
post regular CPL_SGE_EGR_UPDATE messages, so the drivers need to handle
both.
This patch also writes a new parameter to firmware requesting encapsulated
EGR_UPDATE. This allows firmware with this support to not break older drivers.

efficiently read hw eq contexts.
Add cxgb4_sync_txq_pidx() - called by iw_cxgb4 to sync up the sw/hw
pidx value.
Add flush_eq_cache() and cxgb4_flush_eq_cache(). This allows iw_cxgb4
to flush the sge eq context cache before beginning db drop recovery.
Add module parameter, dbfoifo_int_thresh, to allow tuning the db
interrupt threshold value.
Add dbfifo_int_thresh to cxgb4_lld_info so iw_cxgb4 knows the threshold.
Add module parameter, dbfoifo_drain_delay, to allow tuning the amount
of time delay between DB FULL and EMPTY upcalls to iw_cxgb4.

Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op. This leads to a
proliferation of the default_open() implementation across the entire
tree.
Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().
This replacement was done with the following semantic patch:
<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;
|
-f->private_data = i->i_private;
)
-return 0;
-}
@ has_open depends on open @
identifier fops;
identifier open.open_f;
@@
struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,
...
};
</smpl>
