The search for promisc entries was always done on the first port,
While the addition is done on the correct port.
This lead to resource leackage of promisc entries on the second
port and brought to a state where we could no longer enter to
promiscuous mode after enough iterations of "ifconfig promisc"
on the second port.
Fix that by using the correct port when searching.

This patch fixes a bug found by Nish Aravamudan
(https://lkml.org/lkml/2012/5/15/220) where the driver is not following
the spec (it is not aligning the rx buffer on a 16-byte boundary) and the
hypervisor aborts the registration, making the device unusable.
The fix follows BenH's recommendation (https://lkml.org/lkml/2012/7/20/461)
to replace the kmalloc+map for a single call to dma_alloc_coherent()
because that function always aligns to a 16-byte boundary.
The stable trees will run into this bug whenever the rx buffer kmalloc call
returns something not aligned on a 16-byte boundary.

When the interface is down, the hardware is powered off.
However, the suspend handler currently tries to send host sleep commands
(when wakeup params are set) in this configuration, causing a system hang
when going into suspend (the commands will never complete).
Avoid this by detecting this situation and simply returning from
the suspend handler without doing anything special.

Suspending an open usbnet device results in constant
rescheduling of usbnet_bh.
commit 65841fd5 "usbnet: handle remote wakeup asap"
refactored the usbnet_bh code to allow sharing the
urb allocate and submit code with usbnet_resume. In
this process, a test for, and immediate return on,
ENOLINK from rx_submit was unintentionally dropped.
The rx queue will not grow if rx_submit fails,
making usbnet_bh reschedule itself. This results
in a softirq storm if the error is persistent.
rx_submit translates the usb_submit_urb error
EHOSTUNREACH into ENOLINK, so this is an expected
and persistent error for a suspended device. The
old code tested for this condition and avoided
rescheduling. Putting this test back.
