On a Dell PowerEdgeR805, insert a Broadcom®  BMC57710 10Base-T Cooper Single 
Port NIC, and install RHEL 4.7 32 on the system. The installer recognizes 
the card fine, lspci shows it. But no ifup <ethX> fails for that card because 
the kernel module doesn't get loaded fine.

How reproducible:
Always with this card on any system which supports the card

Steps to Reproduce:

1. Install RHEL 4.7 32 bit
2. Do an lspci post-install. The card is shown
3. Try to do an ifup for the card. It fails
4. Check dmesg. bnx2x module loading fails citing vmalloc failure

Actual results:
The card is not able to get an IP

Expected results:
The card should work fine, module should get loaded correctly

Additional info:
sosreport for the system is attached

Customer reports that this card works just fine in the 64bit architecture 
and on both architectures for RHEL5.  They are only seeing this issue 
on RHEL4.7, and they have a one liner patch from 4.8 that supposedly 
fixes this.

Customer also says the issue is related to memory allocation for BAR2 which 
requests 128MB of memory to be allocated. The allocation fails. It is fixed 
in RHEL 4.8. The patch that fixes it is below -

- bp->regview = ioremap_nocache(dev->base_addr,
    pci_resource_len(pdev, 0));

+ bp->doorbells = ioremap_nocache(pci_resource_start(pdev, 2),
min_t(u64, BNX2X_DB_SIZE,
    pci_resource_len(pdev, 2)));


From the other bugzilla (bz#453305 comment#49):

It sounds like they want a backport of this hunk:

    bnx2x: Add support for BCM57711 HW

It would be good to paste the contents of this comment as well as the previous
two into a new bug and copy @broadcom.com, so we can get some endorsement
from Broadcom that we can just take that hunk in 4.7.z.

This patch would be what I would propose for 4.7.z:
