Among the 8390 drivers, so far only ne2k-pci implements that scheme.
This patch implements that scheme for ax88796 and etherh as well, by
making better use of the msg_enable module parameter in lib8390.c.
The axnet_cs and pcnet_cs modules lack the msglevel ethtool ops and the
msg_enable module parameters.
The remaining nine modules lack just the ethtool ops. If you like I will
write additional patches to implement the missing ethtool ops or module
parameters or both (?)
This small patch already addresses the use-case in which the end-user
needs to enable (for example) probe messages for some or all 8390 drivers.
