The git commit
7c5026aa9b81dd45df8d3f4e0be73e485976a8b6 ("tg3: Add
link state reporting to UMP firmware") introduced code that waits for
previous firmware events to be serviced before attempting to submit a
new event. Unfortunately that patch contained a bug that cause the
driver to wait 2.5 seconds, rather than 2.5 milliseconds as intended.
This patch fixes that bug.
This bug revealed that not all firmware versions service driver events
though. Since we do not know which versions of the firmware do and don't
service these events, the driver needs some way to minimize the effects
of the delay. This patch solves the problem by recording a jiffies
timestamp when it submits an event to the hardware. If the jiffies
counter shows that 2.5 milliseconds have already passed, a wait is not
needed and the driver can proceed to submit a new event.

USB: serial gadget: rx path data loss fixes
Update RX path handling in new serial gadget code to cope better with
RX blockage: queue every RX packet until its contents can safely be
passed up to the ldisc. Most of the RX path work is now done in the
RX tasklet, instead of just the final "push to ldisc" step. This
addresses some cases of data loss:
- A longstanding serial gadget bug: when tty_insert_flip_string()
didn't copy the entire buffer, the rest of the characters were
dropped! Now that packet stays queued until the rest of its data
is pushed to the ldisc.
- Another longstanding issue: in the unlikely case that an RX
transfer returns data and also reports a fault, that data is
no longer discarded.
- In the recently added RX throttling logic: it needs to stop
pushing data into the TTY layer, instead of just not submitting
new USB read requests. When the TTY is throttled long enough,
backpressure will eventually make the OUT endpoint NAK.
Also: an #ifdef is removed (no longer necessary); and start switching
to a better convention for debug messages (prefix them with tty name).

USB Storage Sierra: TRU-Install feature update
This patch upgrades the support for the Sierra Wireless TRU-Install
feature (i.e. zeroCD) to allow for future support of Linux enabled
TRU-Install devices.
By default all devices that do not have a Linux enabled TRU-Install
device (i.e. the device does not have a Linux package on the virtual CD
partition) will be switched into "modem mode." Devices that do contain a
Linux package in the TRU-Install virtual CD will be allowed to enumerate
as a CD-Rom so that either (a) a user can install the packaged software
or (b) a user-space application (e.g. udev) can switch it to modem mode.
This patch does allow for manual override by adding a usb-storage module
parameter 'swi_tru_install' which can force the modem into either mode
regardless of what packages it contains.

usb-storage: unusual_devs entries for iRiver T10 and Datafab CF+SM reader
This patch (as1115) adds unusual_devs entries with the IGNORE_RESIDE
flag for the iRiver T10 and the Simple Tech/Datafab CF+SM card
reader. Apparently these devices provide reasonable residue values
for READ and WRITE operations, but not for others like INQUIRY or READ
CAPACITY.
This fixes the iRiver T10 problem reported in Bugzilla #11125.
