- Linux kernel version history:
-
- LK1.1.0:
- - Jeff Garzik: softnet 'n stuff
-
- LK1.1.1:
- - Justin Guyett: softnet and locking fixes
- - Jeff Garzik: use PCI interface
-
- LK1.1.2:
- - Urban Widmark: minor cleanups, merges from Becker 1.03a/1.04 versions
-
- LK1.1.3:
- - Urban Widmark: use PCI DMA interface (with thanks to the eepro100.c
- code) update "Theory of Operation" with
- softnet/locking changes
- - Dave Miller: PCI DMA and endian fixups
- - Jeff Garzik: MOD_xxx race fixes, updated PCI resource allocation
-
- LK1.1.4:
- - Urban Widmark: fix gcc 2.95.2 problem and
- remove writel's to fixed address 0x7c
-
- LK1.1.5:
- - Urban Widmark: mdio locking, bounce buffer changes
- merges from Beckers 1.05 version
- added netif_running_on/off support
-
- LK1.1.6:
- - Urban Widmark: merges from Beckers 1.08b version (VT6102 + mdio)
- set netif_running_on/off on startup, del_timer_sync
-
- LK1.1.7:
- - Manfred Spraul: added reset into tx_timeout
-
- LK1.1.9:
- - Urban Widmark: merges from Beckers 1.10 version
- (media selection + eeprom reload)
- - David Vrabel: merges from D-Link "1.11" version
- (disable WOL and PME on startup)
-
- LK1.1.10:
- - Manfred Spraul: use "singlecopy" for unaligned buffers
- don't allocate bounce buffers for !ReqTxAlign cards
-
- LK1.1.11:
- - David Woodhouse: Set dev->base_addr before the first time we call
- wait_for_reset(). It's a lot happier that way.
- Free np->tx_bufs only if we actually allocated it.
-
- LK1.1.12:
- - Martin Eriksson: Allow Memory-Mapped IO to be enabled.
-
- LK1.1.13 (jgarzik):
- - Add ethtool support
- - Replace some MII-related magic numbers with constants
-
- LK1.1.14 (Ivan G.):
- - fixes comments for Rhine-III
- - removes W_MAX_TIMEOUT (unused)
- - adds HasDavicomPhy for Rhine-I (basis: linuxfet driver; my card
- is R-I and has Davicom chip, flag is referenced in kernel driver)
- - sends chip_id as a parameter to wait_for_reset since np is not
- initialized on first call
- - changes mmio "else if (chip_id==VT6102)" to "else" so it will work
- for Rhine-III's (documentation says same bit is correct)
- - transmit frame queue message is off by one - fixed
- - adds IntrNormalSummary to "Something Wicked" exclusion list
- so normal interrupts will not trigger the message (src: Donald Becker)
- (Roger Luethi)
- - show confused chip where to continue after Tx error
- - location of collision counter is chip specific
- - allow selecting backoff algorithm (module parameter)
-
- LK1.1.15 (jgarzik):
- - Use new MII lib helper generic_mii_ioctl
-
- LK1.1.16 (Roger Luethi)
- - Etherleak fix
- - Handle Tx buffer underrun
- - Fix bugs in full duplex handling
- - New reset code uses "force reset" cmd on Rhine-II
- - Various clean ups
-
- LK1.1.17 (Roger Luethi)
- - Fix race in via_rhine_start_tx()
- - On errors, wait for Tx engine to turn off before scavenging
- - Handle Tx descriptor write-back race on Rhine-II
- - Force flushing for PCI posted writes
- - More reset code changes
-
- LK1.1.18 (Roger Luethi)
- - No filtering multicast in promisc mode (Edward Peng)
- - Fix for Rhine-I Tx timeouts
-
- LK1.1.19 (Roger Luethi)
- - Increase Tx threshold for unspecified errors
