Commit 84eaf4359c36 ("net: ethtool: add get_rx_ring_count callback to
optimize RX ring queries") added specific support for GRXRINGS callback,
simplifying .get_rxnfc.
Remove the handling of GRXRINGS in .get_rxnfc() by moving it to the new
.get_rx_ring_count().
This simplifies the RX ring count retrieval and aligns igc with the new
ethtool API for querying RX ring parameters.

Yao Zi says:
====================
Unify platform suspend/resume routines for PCI DWMAC glue
There are currently three PCI-based DWMAC glue drivers in tree,
stmmac_pci.c, dwmac-intel.c, and dwmac-loongson.c. Both stmmac_pci.c and
dwmac-intel.c implements the same and duplicated platform suspend/resume
routines.
This series introduces a new PCI helper library, stmmac_libpci.c,
providing a pair of helpers, stmmac_pci_plat_{suspend,resume}, and
replaces the driver-specific implementation with the helpers to reduce
code duplication. The helper will also simplify the Motorcomm DWMAC glue
driver which I'm working on.
The glue driver for Intel controllers isn't covered by the series, since
its suspend routine doesn't call pci_disable_device() and thus is a
little different from the new generic helpers.
I only have Loongson hardware on hand, thus the series is only tested on
Loongson 3A5000 machine. I could confirm the controller works after
resume, and WoL works as expected. This shouldn't break stmmac_pci.c,
either, since the new helpers have the exactly same code as the old
driver-specific suspend/resume hooks.

Change do_withdraw() to clear the SDF_JOURNAL_LIVE flag under the log
flush lock. In addition, change __gfs2_trans_begin() to check if the
filesystem is already known to be withdrawn using gfs2_withdrawn().
Then, once we are holding the log flush lock, check if the
SDF_JOURNAL_LIVE flag is still set. This second check ensures that the
filesystem will remain live until the transaction is submitted.
With these changes, it is no longer useful to clear SDF_JOURNAL_LIVE in
gfs2_end_log_write() after calling gfs2_withdraw().

Previously, when a withdraw occurred, we would wait for another node to
recover our journal. This also meant that frozen filesystem needed to
be thawed because otherwise, other nodes wouldn't be able to recover the
filesystem. With the reversal of commit 601ef0d52e96 ("gfs2: Force
withdraw to replay journals and wait for it to finish"), we are no
longer waiting for journal recovery during a withdraw, so we no longer
need to thaw frozen filesystems, either. This also fixes a potential
deadlock reported by lockdep when running xfstest generic/108.
In addition, there is nothing left in do_withdraw() that would require
taking sd_freeze_mutex, so don't bother taking that lock there anymore.

Currently, when a gfs2 filesystem is withdrawn, an "offline" uevent is
triggered that invokes gfs2-util's gfs2_withdraw_helper script. The
purpose of this script is to deactivate the filesystem's block device so
that it can be withdrawn immediately, even before all the filesystem's
caches have been discarded. The script provided by gfs2-utils never did
anything useful, and there was no way for it to report back its status
to the kernel.
To fix that, extend the gfs2_withdraw_helper mechanism so that the
script can report one of the following results by writing the
corresponding value into "/sys$DEVPATH/lock_module/withdraw":
0 - The shared block device has been marked inactive. Future write
operations will fail.
1 - The shared block device may still be active and carry out
write operations.
If the "offline" uevent isn't reacted upon within the timeout configured
in /sys$DEVPATH/tune/withdraw_helper_timeout (default 5 seconds), the
event handler is assumed to have failed.
In addition, add an additional "errors=deactivate" mount option.
With these changes, if fatal errors are detected on a gfs2 filesystem
and the filesystem is mounted with the "errors=panic" option, the kernel
will panic immediately. Otherwise, an attempt will be made to
deactivate the underlying block device. If successful, the kernel will
release all cluster-wide locks immediately so that the rest of the
cluster can continue. If unsuccessful, the kernel will either panic
("errors=deactivate"), or it will purge all filesystem I/O before
releasing all cluster-wide locks ("errors=withdraw").
Note that the gfs2_withdraw_helper script still needs to be fixed to
take advantage of these improvements. It could be changed to use a
mechanism like LVM Persistent Reservations. "dmsetup suspend" is not a
suitable mechanism as it infinitely postpones I/O operations, which may
prevent withdraw from completing.

During a withdraw, we don't want to write out any more data than we have
to, so in do_xmote(), skip the ->go_sync() glock operation. We still
want to keep calling ->go_inval() to discard any cached data or
metadata, whether clean or dirty.
We do still allow glocks to transition into state LM_ST_UNLOCKED. This
has the desired side effect of calling ->go_inval() and invalidating the
glock caches.
Function gfs2_withdraw_glocks() is already used for dequeuing any
left-over waiters. We still want that to happen, but additionally, we
want all glocks to be unlocked.
Finally, we change function do_promote() to refuse any further
promotions.
This commit cleans up the leftovers of commit 86934198eefa ("gfs2: Clear
flags when withdraw prevents xmote").

The current withdraw code duplicates the journal recovery code gfs2
already has for dealing with node failures, and it does so poorly. That
code was added because when releasing a lockspace, we didn't have a way
to indicate that the lockspace needs recovery. We now do have this
feature, so the current withdraw code can be removed almost entirely.

When a node tries to delete an inode, it first requests exclusive access
to the iopen glock. This triggers demote requests on all remote nodes
currently holding the iopen glock. To satisfy those requests, the
remote nodes evict the inode in question, or they poke the corresponding
inode glock to signal that the inode is still in active use.
This behavior doesn't depend on whether or not a filesystem is
read-only, so remove the incorrect read-only check.
