Make sure that userspace passes in enough data when sending a MAD.  We
always copy at least sizeof (struct ib_user_mad) + IB_MGMT_RMPP_HDR
bytes from userspace, so anything less is definitely invalid.  Also,
if the length is less than this limit, it's possible for the second
copy_from_user() to get a negative length and trigger a BUG().

hermas_bap_pread,  hermes_bap_pwrite, and hermes_bap_pwrite_pad all have a parameter "len" that is declared unsigned,
but checked for a value less than zero. Auditing the callers, it is possible for len to be passed a negative value, so len should be an int.

For the four versions of hardware that we (currently) support microcode
download on, the default configuration of our receive interrupt mitigation
microcode was too aggressive, and caused unnecessary delays when pinging,
and low(er) throughput on single connection latency sensitive performance
tests.

This code adds microcode support, and sets the defaults to more reasonable
settings. It also explains the functionality in the code in more detail.
Compile and load tested, shows expected behavior for slight delay of ping
packets (1-2ms) when ucode is loaded, and decent interrupt moderation for
small packets, while maintaining good throughput.

When an error condition is raised by device via D2H FIS or SDB.  sil24
controller should be restarted by setting PORT_CS_INIT and waiting
until PORT_CS_RDY is asserted instead of resetting the controller.
This patch implements sil24_restart_controller for those cases.  This
patch also makes sure that PORT_CS_RDY is asserted on
sil24_reset_controller completion.

Jeff, delay is reduced to 1us and cnt increased to 10k.  My sil3124
turns on PORT_CS_RDY on the second iteration even without any delay.
I think 10k * 1us should be more than enough.

I tried to convert both restart and reset to use msleep's with work
queue, but if we do that, host_set lock should be released after
initiating restart or reset, leading to race condition among
reset/restart, other interrupts and timeout.  Implementing
synchronization among those in low-level driver doesn't seem right.
Well, reduced timeout should work for the time being.

Thanks.

The smc91x driver relies upon register bank 2 being selected whenever
the interrupt handler is called.  This isn't always so, especially if
we have a link change event during PHY configuration.

This results in register bank 0 being selected when the interrupt
handler is called, causing the wrong registers to be read for the
IRQ mask and status.  In turn, this causes us to spin with a
permanently asserted IRQ.

The patch ensures that smc_phy_configure always exits with register
bank 2 selected.
