Hi,
I can independently confirm this regression on Debian 6.12.111-1 with Broadcom BCM57504 / bnxt_en.

We reproduced the failure on two systems:
6.12.107-1 – stable
6.12.111-1 – reproduces AMD-Vi IO_PAGE_FAULT followed by TX timeout/HWRM recovery failure

I backported upstream commit a51d233ccd4889aadb71dace863525cc2b00271e (bnxt_en: fix DMA mapping length for padded small packets) onto the exact Debian 6.12.111-1 source.

The patched kernel has remained stable under the same workload that repeatedly reproduced the issue with stock 6.12.111-1.

Please consider including this fix in the next Trixie kernel update if it is not picked up automatically through the 6.12 stable update.
Regards, R.
