27=======================================
28  This version is used as the base for putback into both s10 and
29  s9u4.
30
31  Following changes were done to this code base before putting
32  back into solaris trees (S10 & S9U4):

92Bug fixes to 4.0.4:
93===================
94   1) bug#4829398 code cleanup for ethernet bootup messages
95
96
974.0.12 code drop from Intel on 3/18/2003
98========================================
99
100  This drop had extensive changes from 4.0.4. Many changes after
101  4.0.4 were realted to new hardware (a.k.a. BayCity chipset),
102  not relevant to Grizzly.After looking at the changelog from Intel,
103  we decided not to do a putback but rather take only high priority
104  fixes from this drop and generate a new version 4.0.4.1.
105
106  Here is the changelog supplied by Intel for this drop:
107
108    ________________________________________________________________________
109    Component Name: Unix-Solaris_8254x_BayCity_Intel
110    Description: Bay City software component for gigabit products
111    ________________________________________________________________________
112
113
114    ---Version: 4.0.13  Date: 3/14/2003 5:00:00 PM---
115    Added transmit mutex locking to the 82547 workaround code.
116
117    ---Version: 4.0.12  Date: 3/10/2003 8:01:00 PM---
118    Added new shared code with LED link speed fix
119
120    ---Version: 4.0.11  Date: 3/7/2003 5:57:00 PM---
121    Updated the Tanacross FIFO hang workaround to reset FIFO pointers instead of sending autonomous packets.
122
123    ---Version: 4.0.10  Date: 3/4/2003 2:39:00 PM---
124    Removed an extra sdu adjustment that was left in by accident
125
126    ---Version: 4.0.9   Date: 3/4/2003 11:13:00 AM---
127    Removed the first call to adapter_stop.  This was called before the HW struct was properly initialized, and could cause hangs.
128
129    Changed reported ethernet sdu from 2024 to 1500, as driver could be configured for invalid frame MTU sizes in Solaris 9.
130
131    Added Tanacross workaround for FIFO hang.
132
133    ---Version: 4.0.8   Date: 2/25/2003 2:27:00 PM---
134    Shared code update including Phy init script.
135    Smartspeed workaround added.  e1000g_smartspeed called from LocalTimer function every two seconds when link is down.
136
137    ---Version: 4.0.7   Date: 2/18/2003 11:41:00 AM---
138    Updated to include bug fixes from the shared code.
139
140    ---Version: 4.0.5   Date: 1/31/2003 10:13:00 AM---
141    Support for new hardware changes
142    Removed the extra ack sent at the end of the attach_req routine.  This extra ack previously made IPv6 plumbing on Solaris 9 fail.
143
144
1454.0.4.1
146=======
147   This version is not an Intel drop but 4.0.4 merged with two
148   high priority fixes from 4.0.12. We will give back the 4.0.4.1
149   driver back to Intel, per their request, so they have the exact
150   code that we are releasing through Solaris.
151
152   The following are the two fixes selected for inclusion from
153   4.0.12 codebase:
154
155   1) Removing the first call to adapter_stop as discussed in
156      4.0.12 changelog.
157
158   2) Corrections to MTU size calculations first introduced
159      in our 4.0.4 putback to bring them into sync with 4.0.12
160      MTU size calculations.
161
162   We also added README file (current file you are reading) during
163   this putback.
164
1654.0.4.2
166=======
167  This version has the following fixes:
168
169  1) bug#4857098: e1000g driver assumes another intel card as its own.
170     The fix involved eliminating 1009, 1012, 1015, 1016, 1017
171     device-ids from e1000g nodelist so that they do not conflict
172     with iprb's subsystem-ids.
173
174     This fix has to be reverted later once we have a proper fix for
175     bug#4859426.
176
177   2) bug#4853683: e1000g lacks a large number of expected kstats
178      The fix involved three steps: a) Renaming some of the existing
179      kstats to comply with WDD documentation b) Computing some of
180      those which are not being tracked c) Supplying zero for the rest
181      the error stats which are not being tracked.
182
183      This fix has to be revisited to improvise the statistics in
184      future.
185
186   3) bug#4862529: System panics during configuring devices on a Dell 4-way
187      servers. The fix involved removing all the devic-ids from nodelist
188      except for 1010. This means that we support now only the grizzly
189      on-board gigabit chipset and "Intel Pro/1000 MT Dual Server Adapter".
190
191      This fix has to be reverted later once we have a proper fix for
192      bug#4859426.
193
1944.0.4.3
195=======
196  This version has the following fixes:
197
198  1) bug#4874857: ipv6 ping fails on bootup for e1000g.
199	 The fix involved implementing multicast tables both at per stream
200	 level and per device level.
201
202  2) bug#4875743: null pointer dereference in ddi_dma_addr_bind_handle.
203	 The fix involved adding LastTxDescriptorBuf to struct e1000g and
204	 handling consequent proper calculations for LastTxDescriptor.
205
206  3) bug#4882541: setting up ethernet address causes machine to panic.
207     The fix involved removing a spurious log message which was causing
208	 the panic.
209
210  4) bug#4883302: Reinstate the removed device-ids - phase 2.
211	 The fix involved some chip initializations to handle 1000 id.
212
213  5) bug#4919285: device id 8086,100e needs to be added
214	 The fix needed for the Intel Precision 350 workstation
215
2164.2.11
217======
218
219We need to sync up with the latest Intel code base for e1000g driver.
220
221Intel is currently at version 4.2.11 while we are on 4.0.4 branch.
222The exact version under 4.0.4 branch is 4.0.4.3. Since we are on
223the branch while Intel is working on the main trunk, we have had
224lot of friction in getting timely fixes from Intel. The current
225syncing up with their main trunk lets us a smooth migration path.
226
227The new code base  also would provide us with support for additional
228cards including Quad port cards (See bugs: 4921433, 4914460).
229In our old 4.0.4 branch, we had to drop support for a lot of cards
230for various problems; with the current syncing up, we would be able
231to support so many various cards except for the cards clashing with
232iprb driver.
233
234The new code base also has support for additional new chipsets. The code
235base also benefits from any fixes to the shared code base with other
236operating system drivers.
237
238The new codebase also has lot of cleanups in terms of various #ifdefs
239and should be much simpler to maintain.
240
241So the list of actual ids take out are:
2421009
2431012
2441013
2451015
2461016
2471017
