Corinna Vinschen 6fe8c74fc9 net: stmmac: fix up RX flow hash indirection table when setting channels 
[ Upstream commit 218c597325 ]

stmmac_reinit_queues() fails to fix up the RX hash.  Even if the number
of channels gets restricted, the output of `ethtool -x' indicates that
all RX queues are used:

  $ ethtool -l enp0s29f2
  Channel parameters for enp0s29f2:
  Pre-set maximums:
  RX:		8
  TX:		8
  Other:		n/a
  Combined:	n/a
  Current hardware settings:
  RX:		8
  TX:		8
  Other:		n/a
  Combined:	n/a
  $ ethtool -x enp0s29f2
  RX flow hash indirection table for enp0s29f2 with 8 RX ring(s):
      0:      0     1     2     3     4     5     6     7
      8:      0     1     2     3     4     5     6     7
  [...]
  $ ethtool -L enp0s29f2 rx 3
  $ ethtool -x enp0s29f2
  RX flow hash indirection table for enp0s29f2 with 3 RX ring(s):
      0:      0     1     2     3     4     5     6     7
      8:      0     1     2     3     4     5     6     7
  [...]

Fix this by setting the indirection table according to the number
of specified queues.  The result is now as expected:

  $ ethtool -L enp0s29f2 rx 3
  $ ethtool -x enp0s29f2
  RX flow hash indirection table for enp0s29f2 with 3 RX ring(s):
      0:      0     1     2     0     1     2     0     1
      8:      2     0     1     2     0     1     2     0
  [...]

Tested on Intel Elkhart Lake.
