[PATCH] qla3xxx NIC driver
This is a complementary network driver for our ISP4XXX parts.
There is a concurrent effort underway to get the iSCSI driver (qla4xxx)
integrated upstream as well.
I have been through several iterations with the linux-netdev list and have had
much response from Stephen Hemminger.
- Built and tested using kernel 2.6.17-rc4.
- The chip supports two ethernet and two iSCSI functions.
- The functions ql_sem_lock, ql_sem_spinlock, ql_sem_unlock, and
ql_wait_for_drvr_lock are used to protect resources that are shared across
the network and iSCSI functions. This protection is mostly during chip
initialization and resets, but also include link management.
- The PHY/MII are not exported through ethtool due to the fact that the
iSCSI function will control the common link at least 50% of the time.
This driver has been through several iterations on the netdev list and we feel
this driver is ready for inclusion in the upstream kernel.
It has been built and tested on x86 and PPC64 platforms.
