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. Thoughts? --
