Some controllers like the XHCI(4) loose track of the data toggle value when
USB receive transfers are cancelled at close. This in turn can lead to to
data loss after the next open.
To avoid data loss, make sure both the receive and transmit data toggles
get reset, before trying to read or write any data.

Some non-compliant USB devices do not implement the

The IFF_DRV_RUNNING flag is used to see if the interface needs
to be temporarily brought down during MTU change sequence.
The problem here is that this flag is cleared in mvneta_stop_locked,
resulting in the reinitialization logic never being executed after
MTU has been changed.
Fix that by saving the flag value before the interface is brought down.

Since IOMMU map entries store a reference to the domain in which they
reside, there is no need to pass the domain to iommu_gas_free_entry(),
iommu_gas_free_space(), and iommu_gas_free_region().
Push down the acquisition and release of the IOMMU domain lock into
iommu_gas_free_space() and iommu_gas_free_region().
Both of these changes allow for simplifications in the callers of the
functions without really complicating the functions themselves.
Moreover, the latter change eliminates the direct use of the IOMMU
domain lock from the x86-specific DMAR code.

If iommu_gas_match_one has to adjust for a boundary crossing, its
check against maxaddr includes 'offset' in its calculation, to ensure
that the allocated memory does not exceed the max address. However, if
there's no boundary crossing adjustment, then the maxaddr check
disregards 'offset'. Fix that.
