stmmac: fix adjust link call in case of a switch is attached
While initializing the phy, the stmmac driver sets the
PHY_IGNORE_INTERRUPT so the PAL won't call the adjust hook
that is needed, on some platforms, e.g. STi, to invoke the glue.
The patch allows the PAL to poll the stmmac_adjust_link just one time
in case of a switch is attached, setting later the PHY_IGNORE_INTERRUPT
flag.
Moving this kind of logic inside the adjust_link it makes sense to
anticipate the check for EEE that will never initialized in this
scenario.

The 82544 has code that adds one additional descriptor per data buffer.
However we weren't taking that into account when determining the descriptors

This change takes that into account by doubling the number of descriptors

hang the Tx ring by loading frames with xmit_more enabled and then stopping

In addition it adds a few more descriptors to account for some additional

e1000: Do not overestimate descriptor counts in Tx pre-check
The current code path is capable of grossly overestimating the number of
descriptors needed to transmit a new frame. This specifically occurs if
the skb contains a number of 4K pages. The issue is that the logic for
determining the descriptors needed is ((S) >> (X)) + 1. When X is 12 it
means that we were indicating that we required 2 descriptors for each 4K
page when we only needed one.
This change corrects this by instead adding (1 << (X)) - 1 to the S value
instead of adding 1 after the fact. This way we get an accurate descriptor
needed count as we are essentially doing a DIV_ROUNDUP().

While it is set in defconfigs it is very easy to miss when updating

So the patch uses the is_pseudo_fixed_link and removes

The driver can manage the mdio registration by using phy-handle,
dwmac-mdio and own parameter e.g. snps,phy-addr.
This patch takes care about all these possible configurations
and fixes the mdio registration in case of there is a real
transceiver or a switch (that needs to be managed by using

Same can be triggered with PROVE_RCU (+ PROVE_RCU_REPEATEDLY) enabled
from tun_attach_filter() when user space calls ioctl(tun_fd, TUN{ATTACH,
DETACH}FILTER, ...) for adding/removing a BPF filter on tap devices.
Since the fix in f91ff5b9ff52 ("net: sk_{detach|attach}_filter() rcu
fixes") sk_attach_filter()/sk_detach_filter() now dereferences the
filter with rcu_dereference_protected(), checking whether socket lock
is held in control path.
Since its introduction in 994051625981 ("tun: socket filter support"),
tap filters are managed under RTNL lock from __tun_chr_ioctl(). Thus the
sock_owned_by_user(sk) doesn't apply in this specific case and therefore
triggers the false positive.
Extend the BPF API with __sk_attach_filter()/__sk_detach_filter() pair
that is used by tap filters and pass in lockdep_rtnl_is_held() for the
rcu_dereference_protected() checks instead.

may be called from the timer handler, and calling the sync shall lead
to a hangup. However, this also triggers a kernel BUG() when the
timer is rearmed immediately after stopping without sync:
kernel BUG at kernel/time/timer.c:966!
Call Trace:

....
It's the place where add_timer() checks the pending timer. It's clear
that this may happen after the immediate restart without sync in our
cases.
So, the workaround here is just to use mod_timer() instead of
add_timer(). This looks like a band-aid fix, but it's a right move,
as snd_timer_interrupt() takes care of the continuous rearm of timer.

This series contains fixes to ixgbe and ixgbevf.
Tushar fixes an issue which was introduced with an earlier commit, where
hardware register RAR0 default MAC address does not get set properly.
Alex fixes two issues, first being the VXLAN port number should be stored
in network order instead of in host order. The second fix corrects the ATR
code to handle IPv6 extension headers. The issue was ATR code was assuming
that it would be able to use tcp_hdr for every TCP frame that came through,
but that is not the case, which resulted in bad filters being setup.
Mark fixes a use of usleep_range() to udelay() in the case where a lock
is being held.
Stefan fixes the offline self tests where ndo_stop() should be used instead
of ndo_close(), which causes IFF_UP to be cleared and interface routes get
removed.
Emil fixes the error case where we need to return an error when a MAC
address change is rejected by the PF. This helps prevent the user from
modifying the MAC address when the operation is not permitted.
